I have tried the below code for comparing images taken from iphone camera. It is working fine. But the problem here is like taking long time for comparing images. Please suggest me the corrections in the below code to compare the images quickly or suggest any alternate methods for image comparison of camera images.

I have tried the -(NSArray)getRGBAsFromImage:(UIImage)image atX:(int)xx andY:(int)yy method for comparing images through the below link. Help is highly appreciable.

Thanks in advance.

If you want to perform high quality comparison, than you will never reach a quick result ... you could however start by down-scaling the take images drastically to for example VGA resolution.
