FX filter, Symmetric Nearest Neighbour
by Roy M Klever
Full source and demo exe
Written in Delphi 2010

Note: Symmetric Nearest Neighbour is now available in TImageEnProc:

I like this filter but it gets quite slow at larger radiuses. If you figure out how to improve the speed I sure would love to hear about it.

Hi Roy,

At a first look, you can get rid of Sqrt function used for calculating variables d1 and d2 (distance), because it's expensive and you repeatedly call it inside 4 nested loops.

As variables d1 and d2 are used only for comparing (if d1 < d2 then begin), calling Sqrt is not necessary (you can compare d1^2 and d2^2 as well).

Hei Siniša,

Yes, that made quite a difference. Even if the result changed a little it is still acceptable. Thanks for the idea! I used this formula so I did not need to use LAB color space, which is quite slow and also would require sqrt in the processing of color comparing.

No I did not use any code from RawTherapee. I do not know that program at all. Actually I could not find any code samples of how to implement Clarity except one that I did not like in VB.

If I come up with a better solution or find some code explaining me the procedure I gone add it here but for now I am just guessing.

Well I did a lot of testing but none gave me the result I wanted. This was the closest I could get for the moment.

Do you have any resources of how it is implemented?

Instead of collecting data only from the whole images user have additional options to collect data from rectangular region or from selection masks.

Note1: I put black pixels on image border after scaling, however, real stuff is to use alpha channel and fill with zeros.
Note2: seam carver class is threaded.
Note3: There is no backward scaling, because it requires rescaling from beginning, or saving seams into some undo buffer (index maps in article).
Note4: enlarging image is not implemented, (it actually should add seams and fill it with average pixel value left+right/2 in case of horizontal scaling).
Note5: There is no object protection, but it's not hard to implement:we can put a high energy value for pixels in selection mask.
Note6: To force object removal, we put negative energy values for pixels in selection mask.
Note7: To preprocess seams indexing, as suggested by article, we can use idle time in application, and start a thread immediately after image is loaded to create index maps.

Yes, very cool algorithm, but a little bit slow.
There are some modifications that trades precision vs. speed.

Original algorithm removes seam by seam, but there are some implementations
that calculate all possible 0 connected min seams on original image
and then perform seam removal (this is also suggested in article's appendix).

I have modified prog. a bit (there were also some bugs in energy calculation) and created separate threads for horizontal and vertical seams calculation without removal. Threads are collecting seams and real removal (and restore) is much faster.

However, I have a problem when there is simultaneous horizontal and vertical resizing...I need to create a new map to resolve vertical/horizontal seams crossing. I'll also try an approach with 0 connected seams.

This demo shows how to do fast "brush" painting with IEBitmap, AlphaChannel and GDICanvas. The demo does not use a traditional "brush". Previous brush drawing demos using GDIPlus all exhibiit slow brush painting that produce intermittent gaps when painting because of the inherent slow speed of TIECanvas drawing speed. This technique has been optimized as much as possible and produces very fast drawing with a smooth continuous brush that can be used for things such as signing signatures on documents, filling information on forms or basic brush painting.

Edit: console program requires grayscale pgm image for calculation.
Program IenSift accepts 24-bit images, which are converted to grayscale and saved as pgm (source.pgm, target.pgm). IenSift invokes console program and
it calculates key features/descriptors and saves them in respectable .kds files. Files (.kds) are parsed and structure (record) is filled with key/descriptor data.

Hi Nigel,

Maybe it's a bug in demo program. On my side it works Ok.



Here are steps for this test:

1. start IenSift.exe
2. Load source image
3. Load target image
4. Click button "Calc. source/target matching"
5. Adjust threshold slider to 0.5

If it does not work, the problem is probably in paths inside the prog.
I will test the demo in clean virtual Windows Xp/7 to see if it works correctly.

EDIT: Got it! It does not work on clean Win xp/7 machines:

Dependent Assembly Microsoft.VC80.OpenMP,processorArchitecture="x86",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="8.0.50727.4053" could not be found.

Console app requires MS Visual C++ redistributable package. As I do have MSVC redistributable package on my PC it worked correctly. More precisely, it requires (VC80) Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package.

In "fast sift" description clearly stands: "A cross-platform library that computes fast and accurate SIFT image features. libsiftfast provides Octave/Matlab scripts, a command line interface, and a python interface (siftfastpy). Optimized with SIMD instructions and OpenMP.

I thought that an author packed OpenMP APIs in siftfast.dll, but I was utterly wrong...what a pity. Too much dependencies.

Hi Nigel,

I have put the answer to the problem in my previous post. The problem is in console application dependencies, which I overlooked.

When I tried it on clean Win xp and 7 installation, the number of detected key-points was 0, which led to console app., that led to MSVC redistributable package dependencies.

It seams that using ready-made console app was not a bright idea, although the app/library is highly optimized.

Edit: I've found a decent source code in plane ANSI C (w/o external dependencies). I'll try to implement it in XE5.

Hi Klaus,

Sorry for delayed answer (I was really busy last few months).
Regarding SIFT, I have managed to compile source code I found on IPOL journal and it works quite well.
It does not depend on any runtime libraries. I'll do some more testing and after that
I'll create a library (static and DLL) and upload it together with demo program.

So, it will be possible to use it from Delphi.

Done!

Here is a DLL and demo application described in IPOL Journal:

http://www.ipol.im/pub/art/2012/mmm-oh/

Source code in C is freely available and I wrapped it up in DLL so it can be used from Delphi. All parameters are described in article on link above and all necessary structures and DLL entries are described in Orsa.h header that goes with this DLL.

Demo application and Orsa.dll do not require any obscure runtime libraries.



Usage: first load source (sample) and target (master) image.
Then you can click Calc. source SIFT descriptor, Calc. target SIFT descriptor and then click Calc. source/target matching or you can click immediately Calc. source/target matching and program will first calculate source and target descriptors and then calculate source/target matching.

After source/target matching is calculated, you can click Orsa homography to run RANSAC/ORSA homography estimation.

There are three output images: Panorama, Registered image 1 and Registered image 2 (same as in demo on IPOL jurnal pages). If two input images are of "panoramic" sort they will be stitched together in panorama output.

Here is demo application (with source code) and DLL (without source code, source code is really messy)

attach/spetric/2016101116368_orsa_distrib.zip
6062.58 KB

Known bugs: you can select background color to fill output images (panorama, reg1 and reg2), but method fill in template class does not work correctly, so use either clWhite or clBlack. It's some obscure template class and I need to carefully examine the code.

Note: Input bitmaps must be of type ie24RGB. Alpha channel is not supported, but I'll try to implement it in future.

Note: To call DLL from Delphi you only need to convert Orsa.h header file to Pascal. There are only structs (records) and DLL entry typedefs.

Have fun,
Siniša

Edit1: orsaIntersection structure in Orsa.h gives intersection box, i.e. a box that encloses a part where two images intersect. It's useful if you want to blend images reg1 and reg2 to avoid visible stitches. Intersection box coordinates are based on target image.

Note: Homography is now included in ImageEn+IEVision. See the demo:

I've tried to call DLL from Delphi, but it crashes, because it's not possible to pass classes (TIEBitmap) across module boundaries, except if
it's linked with dynamic RTL/VCL. In C++ it works flawless.

So, I've modified a DLL and all entries are of the same type. Only arguments
passed are two structures. All images are passed as an array of byte pointers to TIEBitmap scanlines.

Although I'm very clumsy with Delphi, I've managed to make SIFT/ORSA work (hurrah).

Beside that, any reference to VCLs are removed from DLL and it's size shrank to 1.4MB.

So, here is again SIFT/ORSA DLL (2.0) with demo exe in C++ (with source code), but this time with demo program in Delphi (source code only). It can load image (24 bit) and calculate SIFT descriptors.

Orsa.h header file was converted to ORSA.PAS file using Dr.Bob's converter wizard and then adjusted by hand...now this was pain in the....

More experienced Delphi programmers can check Orsa.h vs ORSA.PAS and eventually finish Delphi project that I've started.

Have fun,
Siniša

Once again, output images (panorama, reg1 and reg2) are created the same way as in IPOL online demo. I don't like the way panorama, reg1 and reg2 are created:

output.width = max(source.width, target.width)
output.height = max(source.height, target.height)

and then all output images are translated according to center of the new image, but I didn't want to modify original program. If I decide to make some kind of image stitcher, I'll modify the way output images are created.

Hi Nigel,

There is a bug in DLL: inliners and outliners internal vector lists were not cleared, so when you load new src/target image inliners/outliners vectors data were cumulated (original code is console application, so there wasn't need for any clearing). Beside that I've added translate option (will the reg. images be translated to accommodate new "panorama" output or not). Translate option is added in structure/record (see orsa.pas).

Also, I've modified original image template so that color filling now works ok (I've set green color background in demo).

Level error - for each level (iteration) every new site candidate, i.e. color (luminance) from previously tessellated image at x,y is compared to original image color (luminance) at x,y. if abs(siteLum - origPixelLum) is higher then given error, site is added, otherwise it's discarded. In such a way, areas with similar color are not tessellated (see the figure above - areas on the right side of the image).

NOTE: high number of iterations with high number of sites tend to be very slow (10 seconds and above).

Have fun,
Siniša

Hi Nigel,

Glad you like it. However, it's little cumbersome, because when tessellation is performed, routine returns both voronoi edges and Delaunay triples, so there is no need to run it again and again when mode is changed or edges color is changed.

So, I've changed the logic and added few extra parameters:

1. Number of sites (end): number of sites in last iteration.
2. Number of sites (start): number of sites in first iteration.
3. Custom color: edge color can be picked from ColorBox.
4. Redraw: a button that performs various styles of output (once tessellation is done).

Iterations are simplified: first iteration is started with given sites number (2.) and for each subsequent iteration, number of possible sites is incremented until final sites number is reached (1.).

Also, I have added a possibility to save the image and fixed some bugs (Gouraud shading).

Here is the new version:

Oh well, I really put an effort to build so-so Delphi demo for my drawing engine.

Engine is written in C++ and it's quite fast and lightweight (1.4MB).
I did not build x64 version, but it's not a problem. However, I want to do some more testing and probably some more changes before X64 version.

Also, I need to write a manual on how to use the engine (lot of parameters).
I'll write it down if there is an interest, of course.

Currently only draw-rendering is supported and some options are not exposed in demo program. I'm not "per tu" with Delphi and this was a nightmare for me (volunteers needed). It's a new drawing engine for my prog. Pixopedia and this is a dll version of the engine (almost the same parameters). You can use brush bucket (multiple brushes: speSetBucketIndex function) but it's not implemented in current demo. Setting palette functions are exposed, but not available in demo (you can add them). Demo is built with Devexpress trackbars and color combos, but you can replace them with any others. Initial image is white canvas and right mouse click on the image pops-up available shapes (polyline, polygon and spline are not yet in dll).



Here is dll, demo exe and demo source code:

attach/spetric/2016122217524_delphi_spe_demo.zip
6538.68 KB

Oh yes, I forgot. Currently engine's surface accepts only unfragmented TIEBitmpa(s): IEGlobalSettings().AutoFragmentBitmap := False;

It's not a problem to add a method that can accept fragmented bitmaps, but you'll have to pass an array of scanlines. Any image container that has scanlines or some kind of contiguous buffer with known stride can be passed to engine's surface.

@klaus
Sorry Klaus, I did not have time to put tessellation into engine.
I'm thinking of creating a new dll (it will depend on spEngine.dll) with various effects (tessellation will be the first one).

Hi Yogi,

I think you mean something like this:



I have this option in Pixopedia and it can draw strokes around selection (actually it can draw strokes around multiple selections).
There is no difference between polyline/polygon drawing and selection drawing, as selection is polygon.

However, in this version of dll (let's call it 0.1) I did not implement polyline/polygon drawing (it's actually inside dll, but not exposed).

I will add it in next version (together with selection clipping).

I even wrote a manual (PDF), partially, because in the next version there will be some changes in structures, but not the parameters already in use.

Oh, I see...you are using "free hand" drawing, not en ellipse.

In OnMouseDown event, actually in speHandMouseDown(Shift, X, Y) API,
nothing is drawn, because internally "free hand" drawing calculates
points on the Bresenham's line and so I need two points
X_from,Y_from -> X_to, Y_to.

Furthermore, not all points on the line (X_from,Y_from, X_to, Y_to) are taken into the account, because it depends on the step set (default is 2).

Actual drawing with "free hand" option is performed in OnMouseMove event
(speHandMouseMove(Shift, X, Y) API).

BTW, clear button in demo program does not work correctly, I must correct this.

Yes, you're right, it should draw a brush tip
at point (X,Y). I'll add an option for that in the next version,
something like DrawOnMouseDown := True/False; and then exclude
that point from line drawing in OnMouseMove event.

However, it will work only in slow rendering mode (because of filters).

While I was running demo program, I found a bug exactly in free hand drawing.
In on shape's MouseUp event it was written:

bool TGrapHand::MouseUp(TShiftState Shift, int X, int Y)
{
return TGrapBasic::MouseMove(Shift, X, Y);
// It should be MouseUp from the base class!!!

Raize DropMaster Demos
By Bill Miller Adirondack Software & Graphics
Full Source Demo Projects
Compiled with Delphi 10 Tokyo
Requires ImageEn And Raize DropMaster Components

Raize Graphic Source


Raize Graphic Target


These demos show how to drag images from one application to another utilizing OLE drag and drop. VCL drag and drop does not allow drag drop between applications,
but OLE does. OLE drag and drop is usually implemented by delphi components. I know of three such components:

1. Melander DragAndDrop component- Open source http://melander.dk/delphi/dragdrop/
2. Raize Software DropMaster components- $99 https://raize.com/dropmaster/
3. LMD NG Drag&DropPack- $75 https://lmdinnovative.com/shopping
I recommend the Raize Software DropMaster component because it is easy to use,
works well with ImageEn and requires little source code to implement.

DropMaster is a set of components for adding inter-application drag-and-drop
support to Delphi and C++Builder applications for Microsoft Windows.
DropMaster supports dragging and dropping text-based data, graphics, and
custom formats. DropMaster comes with a collection of more than 40 sample
apps, which represent the results of extensive research into the drag and
drop behavior of many popular commercial applications.

I have used the Melander DragAndDrop component in older versions of Delphi but is several years old now and unfortunately, I have not been able to get it to compile in Delphi Tokyo.

These demos consist of two applications:
1. DropMaster Graphic Source Demo
2. DropMaster Graphic Target Demo

The Graphic Source Demo allows dragging an image from TImage and TImageEnView to OLE enabled drag and drop applications such as Microsoft Word, Microsoft Edge and the DropMaster Graphic Target Demo.

LMD NG DragAndDrop

These demos consist of two applications:
NGDropTarget Demo which uses TNGDropSource to configure dragging data and initiate drag&drop operation (source side).


NGDropSource Demo which uses TNGDropTarget to receive dragging data by registering some application's control as a drop target and providing related events like OnDragEnter, OnDragOver, OnDragLeave, OnDrop; and a single OnDragAction event, which can be used instead of all previously mentioned events to simplify code.

Lips - Lua Image Processing System

The core of the system are two DLLs: lipsEngine.dll and ocvWrapper.dll.
The first one deals with LuaJIT engine, the second one is a wrapper for a limited set of OpenCV 4.0 filters and image processing routines.

The architecture is very simple:
Host application (C++/Delphi) -> lipsEngine.dll -> ocvWrapper.dll.

Note for Delphi users:
To use Lua engine you need to convert lipsEngineDLL.h and lipsGlobals.h to respective pas files.
If you want to use ocvWrapper.dll directly from Delphi, you need to convert ocvWrapper.h and ocvGlobals.h to respective pas files.

Few host application screenshots:

This is a demo of TIERichEdit. I just modified the provided demo to include some useful features. The .EXE was compiled with 10.3.
Free.

Be sure to update C:\ProgramData\ImageEn\Source\ie.inc and update to make sure it is in your library path.

ie.inc now look like this:
// Support for Find and Replace dialogs in TIERichEdit (8KB)
{$define RichEditFindAndReplace}

// Support for popup toolbar for TIERichEdit and TIETextLayer (trims about 5KB)
{$define RichEditPopUpToolbar}
There are additional options for using TIERichEdit that are not needed by the demo.

I did not succeed in using the internal Find/Replace for TIERichEdit. But those are based on TFindDialog and TReplaceDialog so I just used those dialogs. I have attached the modified demo program, in hopes that someone else will benefit from a decent starting point. It includes the source code and is free to all.

In the demo I added a menu bar with a set of options for Find, Next, Previous, and Replace. I've never seen code for searching backwards in a TRichEdit, but TIERichEdit supports this both with the backwards search option in TFindDialog and with the code I've provided in the Previous menu option.

I felt it was worth using TIERichEdit because I liked the URL launching, backwards searching, popup toolbar and image pasting. There are other possible areas to benefit but my current project doesn't require them - yet. That includes the ability to import DOCX and PDF files. I did add error traps for those features using the CanImportExport function.

2/5/2020
I found a bug in the code for finding Previous in the FindDialog1Find and the Previous menu option: FindPrevious. In both cases the section of code for backwards searching should be changed to:

begin //backwards searching
mySearchTypes := mySearchTypes + [stBackward];
StartPos := imin(SelStart, SelStart + SelLength) -1;
ToEnd := StartPos + 1;
end;

NiGulp 0.9

Fully functional (well, I hope so) application for enumerating and executing Photoshop 8bf filters via pspiHost engine. Uses ImageEn for loading, viewing and creating filter mask from selections. 32 and 64-bit binaries with source code available on GitHub.



Binaries and complete source code:
https://github.com/spetric/Photoshop-Plugin-Host/releases/tag/v.0.9

For more info check:
https://github.com/spetric/Photoshop-Plugin-Host/blob/master/NiGulp/Readme.md

Note:
- all pspiHost API calls can be found in frmNiGulpU.cpp
- call-back functions can be found in TNhelper.cpp

I hope I wrote readable source code and it can be easily translated to Delphi.
Thanks Nigel for C++ to Pascal headers conversion and for testing the engine with Delphi.

Hello Spetric,

Thanks for releasing Plugin Host for 64bit.

I have personally have been waiting for this for quite some time.

On initial testing it is working like a charm!

I have one request:
How can we execute a plugin so that it applies its effects without showing its UI.... Can you provide some way by which we can do this?

TIA

It can be done: First time, filter is called with UI and other times it can be called without UI with saved parameters. However, I did not implement this feature. Maybe in one of the next versions. Bugs first, then big documents for newer 64-bit filters, etc...

Hello All,

You can download Photo Sense from here: https://www.insidelogicsoftware.com/

Please open this link and click on "Free Download" button to get the software. It is FREE!

Special thanks goes to (in no particular order):
- Siniša(Spetric) for sharing his hard work which allowed us to add support for third party Photoshop compatible filters.
- Bill Miller (w2m) for your sample codes and posts has taught us many things.
- Roy M Klever (rmklever) your Picture Color EQ got us started on how to implement lightning fast color/tone/etc. corrections and we have implemented an AI based photo correction in may of our Image->Adjustments.
- Ma Xiaoguang and Ma Xiaoming (twin brothers) who helped in implementing a perfect Levels feature which gives result equivalent and at times better then other tools in the market.
- Last but not the least to IE and Nigel without whom we would not have thought of building such a tool.

Hi Kursat

You don't need an external library for SVG vector support. You can use the ImageMagick plug-in from our download page. I've added a demo in 10.0.0 showing how to do render SVG layers:

\Demos\LayerEditing\SVGVectorLayers\SVGLayers.dpr

You can run it directly too:

https://www.imageen.com/files/demos/run/LayerEditing/SVGVectorLayers/SVGLayers.zip

I like your CreaLesson app. What is the method you use for the chalk text effect?

Hello All,

We have just updated our world class photo editing and designing product PhotoSense.

Now we can safely say that it is the best alternative to Photoshop and many other main stream image editing software.

I want to mention one notable feature and that is we have integrated AI in image correction functionality so that a user can make better image corrections with minimum of efforts and get consistent results.

Another very powerful and notable feature is Cutout. It is the worlds fastest & easiest and it is non destructive!!

The Feature List is very long so instead of pasting it here I would ask you to visit our product's website and see for yourself.

You can download PhotoSense from here: https://photosense.net/
