How to I detect a document in a scanned image?

I have a scanned image of multiple invoices (i.e. multiple invoices/slips on one image). They therefore have no borders in the image. it's just white everywhere except for the text of the various invoices.

How do I detect the individual invoices in such a situation?

Thanks.

You forgot to attach any images. Are they in a regular pattern, like an invoice in each quadrant? If so, try to scan them like that. It will make the image processing so much easier. If they can't be scanned properly, like someone just dropped them on the floor at random locations and orientations, then took a photo with their phone, then say why that is the case. Then demand that that person get appropriate training on how to create an image. As usual, the image processing can eliminate a lot of post processing "corrections" if the image is just taken properly in the first place.
