Application Form Validation using OpenCV

Question

The task is to validate the application forms which were being scanned. The forms must be validate against the template form to detect whether they are dirty, different or not scanning properly(rotated or only being scan halves).

I'm using template matching currently and using the max value as the threshold to validate them. Are there any other good alternated solutions to validate them. Any kind help is appreciated.

Answer 1

may you want to have a look here Contour Analysis for Image Recognition in C# Basically this approach lets you compare descriptors of shapes. It is very powerful and fast, takes different rotations or scales into acount, but you will get into serious trouble if the scan is malformed.
