Hi RV,

Your code is interesting.

I am attaching another code for extracting ROI from grayscale or RGB image. When i use the image in second attachment some it give invalid image. Not sure why. Could you figure out. Also, if you could see how can i "fit to window" in the ROI constrcutor pop up window since the image has to be scrolled due to its larger size. ..Thanks

Just select rectangular ROI which will cover entire image (ROI's width and height should be equal to image's width and height)
