Hello i am looking into computing the affine transformation of one image onto another image as is done using the Lucas Kanade Algorithm or inverse compositional algorithm in active appearance models. The difference being of course that i am not interested in warping many points in order to match faces but in matching just one template image with another image with a affine transform in real time (the template and image are really small). Is there any build in functionality in opencv i can use to do this?
thanks
