Corelation betwen Images - Looking for algorithm

igorbog · Jun 2, 2011

Hello
I'm looking for a simple correlation algorithm:
I need to find a small picture on a large one. Later it will be used on FPGA board.
Somebody know good and simple correlation algorithm
Thanks

Here, a code wrote in MATLAB language :

Be aware that pattern matching based in correlation algorithm, is scale invariant.
Check if there no are restrictions in your target application to this constraint.
