Image matching

asked 2012-12-19 03:49:49 -0600

We are about to start a big project where image matching is a central function. We want to know wheter Open-CV is a sufficient Tool for that. We got a very big master image and a number of discrete images taken from above the master image. Now we want to find the exact position, orientation and scale of the smaller image in relation to our master image. Do anyone have experiance with similar functionality? Can you give us an idea on the efficiency of the involved algorithms?

Thanks.

You can refer Features Finding and Images Matching for extract some features and matching . For exact matching you can refer Template Matching where opencv has inbuilt function for doing this. If your discrete images a are the exact copies from the master image, template matching might be a good method.
