Abstract: A new robust feature-based image registration algorithm was presented. This algorithm employs the affine geometric invariant in the design of feature descriptor by constructing feature areas, which enables it to deal with affine geometric deformation. Since the feature descriptor, which has a small amount of calculation, is only determined by coordinate information and independent of the gray scale information, this method has good timeliness and is robust to the gray scale discrepancy between the images.  

Key words: image registration, affine deformation, geometric invariant
