Multi-resolution image registration based on correlation technique

This paper proposed the new techniques of the multiresolution image registration. The two images (reference and searching images), firstly, were prepared by decompose to multiresolution images with discrete wavelet transform (DWT). Then the factional masks are created and convert to the binary masks base-on prior information. This efficiency mask-based algorithm operates in the coarse-to-fine resolution fashion on low-pass subband of decomposed image. Then the correlation performed at each resolution level to accomplish the registration problem KeywordsMultiresolution, images correlation
