What is it for ?

Scanning image to find sub image, like a CIDetector but to detect targeted images.

Really? but what is it for ?

I'm working on a lot of Bank applications and in order to execute functional testing i fix the constraint of logging on real testing accounts (protected by secure keyboard) using this library.

The idea, i have a master image (here, a secure keyboard to analyse).

I want to find a sub image (here, all the pieces of the keyboard).

I am running pixel scanning on the targeted keyboard for each pieces.

The result :)
