Index Algorithm and Its Application on Image Multiscale Transform
索引算法及其在图像多尺度变换中的应用

This paper presents several models of index algorithm and analysises,the property of lifting wavelets transform.To solve the problems of the space needed for the index-matrix,we change the 5/3 wavelet,and propose a novel image multiscale transform method.The dynamic ranges of both high-frequency coefficients and low-frequency coefficients generated by the proposed new transform are the same as those of the original input image.Thus,the multi-level reversible index transform is realized.The experimental results show that the implementation of the multiscale transforms based on index method is faster than that of the general method.
