yogiyang	Posted - Dec 24 2014 : 23:44:28 The subject says it all. I have a need wherein I have to allow user to select two different images (and load them in two separate ImageEn Controls) and then show the difference between two images in a third ImageEn control. The difference has to be calculated based on either light values (brightness) or color values. I don't know as to how I will be able to achieve this so any hints or small sample code will be of great help. TIA Yogi Yang Yogi Yang

xequte	Posted - Dec 28 2014 : 17:54:28 Hi Yes, that should not be hard to do. Are you referring to the result of CompareWith or your own algorithm? Nigel Xequte Software www.xequte.com nigel@xequte.com
yogiyang	Posted - Dec 25 2014 : 22:52:46 Thanks Nigel, This works like a charm. Would it be possible to create a mask or selection from the resulting image and apply the same to user selected image? TIA Yogi Yang
xequte	Posted - Dec 25 2014 : 03:52:37 Hi Yogi There is the CompareWith function (see the "Show Image differences" demo), but it only works on pixel intensity: http://www.imageen.com/help/TImageEnProc.CompareWith.html So you may be better to write your own algorithm which resamples two images to the same size and then compares the individual pixels (via scanline).
