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

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

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.
