i have segmented image... the unwanted portions are replaced by zero...
now i wanted to find the maximum and minimum value of the segmented regions...
but as i have assigned unwanted portions as zero, everytime minimum value comes as zero... but for some images the segmented portion contains value zero, so how to take the minimum and maximum value from the segmented portion only...

roi = repmat(binaryImage, [1,1, size(origImage,3)]);
origImage(~roi) = 0;
max(origImage(roi))
min(origImage(roi))
