Nigel, Alpha Controls always supported skinning for ImageEn. I've been using them for many years without problems.

Regarding statistical color correction by @rmklever;. I have implemented Roy's code in C++ with two more options: collect statistical data from given rectangular region(s) and collect data from selection mask(s). Instead of collecting data only from the whole images user have additional options to collect data from rectangular region or from selection masks. Those options are not so hard to implement and results are very nice.

I've put some examples on my FB page: https://www.facebook.com/Pixopedia/

Picture Color EQ
Delphi 2010, Source code and exe demo :)
by Roy Magne Klever



Download: www.imageen.com/files/other/coloreq.zip

I was testing an idea I had and it turned out to be quite useful, at least for me. Hope you find it interesting and useful too.

Hello Roy

Color Picture EQ

It is Possible to delete the Selected Color, Using Transparency, Through Alpha Channels?

Thank you so much.

Here is a demo on how to use SpHost library (8bf filters).
SpHost is small 94k library and it executes 8bf plugins (filters). Library must be included in your project. Not all filters will work! Complete source code (both demo and SpHost) is inside zip. Demo is provided with few freeware filters.



Usage: Load plugins, open image, press Execute.

Note: some filters require plugin.dll which can be downloaded from the net.

Note that header files are from old PS SDK. If you want to make your own host plug-in you should download the newest SDK version.

Pantographic Cellular Automata Inpainting:





Exe and source code:

attach/spetric/201629165612_paca_inpaint.zip
3017.04 KB


Note1: this is quite rudimentary version, just an idea. Fully automated version
requires multi-resolution CA and contour analyzing.

Note2: it does not work well when trying to automatically remove object
from image with strong diagonal contours (such as shown above).
Manual adjustment is necessary.

Have a nice time,
Siniša

Edit: to change matrix logical operator, just click on it (except central element). For more info check http://www.sigmapi-design.com/media/Coupled_Map_Lattice_Brush.pdf


Edit: missing files (project, res)

Ellipse rotation:


Draw ellipse and rotate it. Ellipse is created from polyline points calculated in grapEllipse object.

Parameters:
Resolution - higher the number, less points are used to construct final polyline.
Rotation trackbar - obvious


Exe and source:

More "fancy schmancy" approach would be to check if ctrl or shift button is pressed (in OnMouseMove event) and to rotate ellipse using mouse.

Note: when resolution is set to small number, rotated ellipse is little bit jagged.

Hi Sinisa

Nice work with the inpaint project; I had fun playing with this one. I look forward to seeing it develop further.

You might want to add some hover hints as there are many options to work with.

Besides midpoint, I have implemented another algorithm (trigonometric/general ellipse), so you can switch
between those two algorithms in any time to see the difference.
With trigonometric/ general ellipse method, polyline is less jagged, because of floating point (double) calculation of output points. If there is an interest, I can upload the updated version.

I was experimenting with image energy and min-energy seams and this came out as a by-product. Original article: http://perso.crans.org/frenoy/matlab2012/seamcarving.pdf

Seam carving (content aware scaling).

original image:


scaled (by x):


Exe and source code:

attach/spetric/20162158835_seam_carving.zip
2992.39 KB

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.

Wow, it's impressive how much the seam can be reduced without noticably affecting the subject.

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.

TIEFileDragDrop To TImageEnMView Demo
by William Miller/Adirondack
Full Source
Compiled with Delphi Seattle, but is expected to compile with Delphi 2010 or higher.
Price: Free


The TIEFileDragDrop To TImageEnMView Demo shows how to drag and drop images from the windows shell (File Explorer) to TImageEnMView.

TIEFileDragDrop is not documented for use with TImageEnMView so a brief overview is shown below:

Create a AFileDrop: TIEFileDragDrop; declaration.
AFileDrop: TIEFileDragDrop;

Create a TIEFileDragDrop class in FormCreate:
AFileDrop := TIEFileDragDrop.Create(ImageEnMView1, DropFiles);
Create a Private declaration DropFiles method
procedure DropFiles(Sender: TObject; ssFiles: TStrings; dwEffect: Integer);
Do not explicitly free the AFileDrop object so register a expected memory leak in FormCreate:
RegisterExpectedMemoryLeak(AFileDrop);
Activate dropping in FormCreate:
AFileDrop.ActivateDropping := True;

Download: attach/w2m/2016321105225_TIEFileDragDrop.zip
122.91 KB

Note: Some exception logging Delphi add on's like EurekaLog may show a memory leak even after registering the memory leak, but this is a false positive according to the developers of ImageEn:

"It is best to the let the application handle the freeing of TIEFileDragDrop. Of course then you will get a warning from your memory management tool so you need to register the expected leak (not that it is actually a leak. The object exists for the time of the application and is destroyed when the owner is destroyed).", Nigel Cross
