Hello! I would like to ask, how can I use impoly to choose all the ROI and not just the polygon that is around it!

mask = createMask( hROI, hIm );
should give you a binary mask for the region, where hROI is your impoly and hIm is the handle of image on which it was drawn.

This will apply the mask to the original image to erase the original pixels everywhere outside the mask:
% Initialize output to be same as input.
maskedImage = grayImage;
% Now erase pixels outside the mask.
maskedImage(~mask) = 0;
