I have a mask(mask is for an image) which is saved in .mat format. Now, i want to take the boundary of this mask. Is it possible to convert from mask to boundary? Can anyone kindly guide me?

Yes. Use bwboundaries() to get a list of (x,y) coorindates. Use bwperim() if you want an image of the outer boundary.

Well you just have to figure out what the variable names were when they were saved, and then get back those same names, and make sure you're using the right one in the right place. It's just bookkeeping really. I mean, if the name is maskedRgbImage, it's probably an RGB image and don't use it where a gray scale image or binary (logical) image is expected.
