Study on Subpixel Registration Methods based on Wavelet Analysis

Image registration is an important task in the field of computer vision and pattern recognition. And the applied values is also reflected in the study of remote sensing, medical imaging and the object indentifying of multi-sensor fusion. In this paper, a new subpixel registration methods which based on wavelet analysis was proposed by improving polynomial subdivision algorithm and pixel level registration. Furthermore, the precision of the method was also analysed after the process. The simulation results shows that the method in this paper achieves good effects and reaches the precision of sub-pixel.
