Hi I have a question. I have a grayscale image, I chose a region using imfreehand command and I have its position. I can convert to the mask but that is a binary image how can I extract the exact image that is correspond to region of imfreehand from the grayscale image. Meaning that imcrop returns the cropped version of grayscale image I want to do the same thing here.
Then I like to have something like image(pos) to extract the portion from grayscale image. However this is of course is a error because the subscript is a fraction.
