Abstract :
This paper proposes a multiresolution coarse-to-fine algorithm to align images. By using a hierarchical strategy, we can improve the execution speed and iterative convergence properties. Our optimization procedure uses the standard Levenberg-Marquardt method and the gradient of the image with respect to the alignment parameters to solve the general registration problem. Our algorithm is applied to align images undergoing affine, perspective and bilinear transformations. In the experiments, we show that our registration algorithm generates precise registration parameters
