An Algorithm on Geometric Global Registration of Parallax Images Based on Wavelet Transform
基于小波变换的视差图像全局几何配准新算法

To solve the quick and robust registration of parallax images, a coarse-to-fine global registration strategy using the coarse images weighted with detail image was proposed.Taking the advantage of multi-resolution characteristic of wavelet transform,a gray pyramid was built by the wavelet transform of images,and the approximate components of each layer was matched layer by layer from top to bottom.To improve the reliability of registration ulteriorly,the optimized registration was gotten from the weighed correlation registration of approximate components with vertical details in the penultimate layer of the pyramid.
