Registration of images with affine geometric distortion based on Maximally Stable Extremal Regions and phase congruency ?
A combination of coarse alignment and refinement is employed in the method. Input images are coarsely aligned by fitting and normalizing the matched MSERs. A phase congruency and point set registration based refinement step is used. The method accurately and efficiently aligns images with affine distortions. The method is robust to illumination changes.
