Hi , I have a grayscale image for which I need to do some segmentation and find cells. after which I need to show the segmented cells on top of the original image . but I need the perimeter of the cells to be in color and indexed so I can see how many cells I found.
I have done the segmentation and found the perimeters of the cells but how do I show them on top of the original image?
I got confused with the alphadata property and all other options.. thank you

If you just need the perimeters, use bwboundaries(), and then turn "hold on" and then use plot() to plot the outlines/boundaries/perimeters.
