Hi Everyone,
I need some help with a problem I am dealing with now. The problem can be summarized as follows:
· I have images that I have divided into pixels with known dimensions (width x height) . An image is about (1024X943) "965632 pixels" in total. · The problem is that I need to calculate the area of a part of the image (irregular shape). So how can I draw an irregular shape (maybe using imfreehand tool) and determine the number of pixels inside it?
Thanks a lot in advance, Mariam

See my image segmentation tutorial: http://www.mathworks.com/matlabcentral/fileexchange/25157-image-segmentation-tutorial
Also, I've attached some demos using imfreehand() if you want to trace your object.
