Auto Crop Picture From Scanned Document?

[Shohag_ifas]

Greetings,
hope all member of this forum are fine..

i am working on a project where i have to scan a lot of pages (application form) where each form is attached (pasted with glue) with application picture. So, i need to get the picture (crop only the picture) from that scanned page/document.

I have attached a sample..

i can set the exact location on the document/image but few issues with that:
1. attached/pasted image is not on same size..
2. it may be not be pasted on same place on each form
3. it may be rotated slightly..

so, i am looking for some automated process that can take out the picture correctly regardless the above issues. i assume face detection may be the tool, but i am not sure about that..

so, it would be great if any one can help me with that?

thanks in advance

any help will be highly appreciated...

take care (every one)
may Allah bless all of you
best regards
