Hi to all

I have graduate project, and the problem of it is:
How to extract the handwritten characters from table boxes?
For example this is the original picture:

And I want it to be as this:

I suggested in the project proposal to use Projection Profile method (X-Y tree) or Hough Transform method to find the straight lines in the image which are (table boxes) and remove them.

I have tried to apply Projection Profile method (X-Y tree) in MATLAB but I didn't find code or algorithm for it. Then I tried to apply Hough Transform method, but I didn't success totally with it, also I don't know how to delete the straight lines after found them?

So, this is my problems that i wish find solutions for them with anyone can help.

Thanks.

ALI.
