Research on Automated Image Registration Technique for Visual Image Based on Wavelet Analysis

To develop a quick,accurate and antinoise automated image registration technique for visual image, the wavelet analysis has been used to extract the feature points in two images followed by the compensation for input image with angle difference between them. A hierarchical feature matching algorithm has been adopted to get the final transforming parameters between the two images. The simulation results for several visual images in some fields show that the method can quickly, accurately and automatically register these images and is antinoise to some extent.
