Abstract It’s a key problem to search for affine invariant with respect to translating, scaling, rotation and skewing in multiresolution analysis. Based on affine invariants defined in Affine Invariants for Object Recognition Using the Wavelet Transform, the original absolute affine invariants are improved in this paper. After the analysis of the invariants, their limitation is pointed out and a new kind of absolute affine invariants is defined. Both experimental results and analysis show that the proposed invariants can be easily applied to image recognition.
