Hello,

I have a few questions regarding IEVision as follows:

  • Which version should I use ievision.dll or ievision-mp.dll?
  • From where can I get my hands on the source of the demo BackgroundSubtractImage? I am asking this because this demo is not included in the setup that I downloaded and installed but there is a demo available in the demo section of web site (https://www.imageen.com/files/demos/run/IEVision/BackgroundSubtractImage/BackgroundSubtractImage.zip)
  • When I use SubtractorObject.Apply( BackgroundImage.GetIEVisionImage(), 1 ); in my 64bit application it gives c000008e FLOAT_DIVIDE_BY_ZERO. Why? Again if the code is compiled in 32bit it works.


TIA

Yogi Yang

Hi Yogi

If you are using OCR using the MP versions (twice as fast with OCR). If you don't use OCR, just use the normal IEVision.

See: http://www.imageen.com/help/ImageEn_DLLs.html

Demo is available with the 5.4.1B installer. Also attached...

I can reproduce the 64bit issue and we are investigating.

Hello,

I forgot to mention that SubtractImage demo is also mentioned on this help page: https://www.imageen.com/help/TIEVisionBackgroundSubtractor.html.

And I am trying out the code on this page. The exact fragment is:

// "Learn" background
SubtractorObject.Apply( BackgroundImage.GetIEVisionImage(), 1 );
// Pass subject and get foreground mask
fgmask := SubtractorObject.Apply( ForegroundImage.GetIEVisionImage(), 0 );


TIA
