They are called “Mobile Pocket Document Scanning” What each of them does is take a photo of the file through the iPhone camera, and then they find the angle/position of the file (because it is almost impossible to shoot directly), straighten the photo and readjust the brightness and then turn it into a pdf. In the end The result looks like a scanned document.
Look at the actual application of one of the applications Genuis Scan:

It seems difficult to implement, but I think there is a clever stackoverflow that can point me in the right direction!
Does anyone know how to develop something similar? What kind of library or image processing technology do you think they are using? Anyone know if there is open source software available?

I am looking at CamScanner, Genius Scan and JotNot and trying to figure it out How they work.

I found an open source library that can solve this problem:
