I have image of Tiger's Pugmark (footprint impression) on mud. I want to detect the boundary of the pugmark but the image is uniform in intensity that is foreground and background cannot be distinguished based on intensity variations. What can i do to distinguish between the pugmark and the background.

Try thresholding and texture filters, like entropyfilt() and stdfilt(). It will be tough, particularly where the pawprint is not very well outlined. I can imagine you could have some parts that don't have a clear and distinct outline - it just kind fades away.

Looks like a Sobel filter to me. You can do that with conv2() or imgradient().
