Hi All,
I have installed the release 5.3.0.0 and have executed four test
1. no access to either ievision.dll or ievision-mp.dll & vcomp140.dll as control test and no OCR was able to be executed.
2. provide access to ievision.dll and performed a full-page OCR test which took about 7 seconds.
3. provided access to ievision-mp.dll & vcomp140.dll and remove access to ievision.dll and ran the same OCR process which took 11 seconds.
4. provided access to ievision-mp.dll & vcomp140.dll and ievision.dll and ran the same OCR process which took 8 seconds.
VM, Hardware has a 2 processors.
My question is why is it faster using the ievision.dll support file than the ievision-mp.dll & vcomp140.dll?
Thanks
Ron |

Hi Ron
Most importantly, you have not mentioned whether you were running under Delphi, which will skew your results.
The MP versions use Tesseract's OpenMP support to use multiple cores to improve processing throughput. On a system without many cores there may be a cost to using it. On a system with many cores there is significant benefits. On my test system (i9-9900K with 8 cores) the gains were impressive: 55% faster with 32bit application, 56% faster with 64bit application.
Other results from my testing:
- OCR under 64bit is 10% faster than 32bit
- Running under Delphi slows processing by 50%
- Performance benefit between OpenMP and non-OpenMP is not as great running under Delphi, about 37%

We have installed the support files on some client systems and were getting an error that the vcomp140.dll is not designed for their system. What are the OS requirements to use the vcomp140.dll and ievision-mp.dll files?
Thx

Hi Ron
It should work in Windows 7 or newer. Also, check the bitness, i.e. not running a 64bit EXE and DLL on a 32bit system.

| Their machine is an x86. So is the distributed version of the vcomp140.dll for 64 bit machines only? There is only one copy of this file in the imageen folder. |

Hi Ron
There should be a 32bit version of vcomp140 in the IEVision install folder:
\Binaries-OpenMP-32\

| There's the rub that folder is not in the IEVison folder. I'm using version 5.4.0. |

Hi Ron
You need 5.4.1B, which is IEVision_5.4.1B_3990_RG_Setup.exe
Please email me, or request the download again. It is fully compatible with v9.3.0.

Hi Nigel,
I installed the new 32bit binaries 5.4.10 and have some problems. The ievision.dll not loading while the ievision-mp.dll and vcomp140.dll work fine. I removed these binaries and put in place the 5.4.0.0 version work fine. Please advise.
Thx
Ron |

Hi Nigel,
It seems that I made a mistake. Both types of support files for version 5.4.1.0 or not working/loading on my original 5.4.0.0 version files still work.
Sorry

Hi Nigel,
After further testing with the 32bit ievision-mp.dll and vcomp140.dll v5.4.0.0 files, I found that after scanning a document and perform an OCR process the scanning and OCR produced no results and no errors. I reverted back and forth using just the ievision.dll and the MP version and only the none MP version worked as expected and consistently. Is there a logging method I can enable to help you track this problem down?
Thx
Ron |
