From: ImageAnalyst on 1 May 2010 10:52 Just write the value (say, 255 or [255,255,255]) directly into the image (the numerical 2D array) and use imwrite to save that array out to disk. E.g., for the top line (line 50) of the box going from column 100 to column 150: imageArray(50, 100:150) = 255;

Can I still watch the sequence of frames by using implay() if I modify the arrays like this? |
