I have a sample of handwriting. And I want to find the left, right and top margin[i.e., the space between the starting of the writing and the edge of the paper to the left is the left margin]. Please help me with the code.

Did you try to threshold and then use regionprops(L, 'BoundingBox')?

If the shadows on the paper are a problem then call edge() first and then get the bounding box from the edge image.

Then I still don't know what you mean by "without converting it into rgb." when it's already RGB. What does "margin" mean? You forgot to post an image where you show the wounds and the margin. Please do so in a new thread and outline them in red or something.

I suggest you post your two images in a new thread, your own, rather than here in @Poornima Gokhale's discussion.

I don't want to answer your question in @Poornima Gokhale's discussion. So like I said, start your own question somewhere else (NOT here) and I'll answer there. @Poornima Gokhale probably doesn't care about your problem.
