How to find the margin in an image of the text document?

10 views (last 30 days)
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.

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.
