How to detect/segment/extract curves in a grayscale image? for e.g. I am using a medical image such as thermal breast image.I would like to detect the lower breast boundaries such as parabolic curves and remove the portions below it.

Since you haven't provided an image, I just recommend you look for a published algorithm here: http://iris.usc.edu/Vision-Notes/bibliography/contents.html Anyway, we don't do algorithm development, just answer MATLAB questions on syntax, error messages, program flow, etc. There are lots of papers there on medical images. If you just want masking , I might be able to help with that.

It's where you make everything inside or outside some polygon a certain color, like black or white like the attached examples.
