What is the best way to modify existing VOS/IOS code to implement some image processing algorithms. For starters, I would like to be able to have a real-time video stream on the GUI, with some image processing layered on the top (Hough lines, Sobel, etc.). I tried modifying gapoFrm -> pFramePtr and gYFrameOut pixels (setting them all to 0, black, for example) in the SendFrameData function (gui_framework.c). Unfortunately, after flashing the new image file the functionality remained the same.
Thank you in advance!
