QU Xin-liang · Zhongguo yixue wulixue zazhi · 2006
The adaptive threshold method in fractal domain is used to wavelet fractal domain.It solves the adaptive matching error of wavelet tree R and matching tree D in fractal quadtree coding based on wavelet transform.The experiment results show that the adaptive threshold method improves the adapt of fractal quadtree coding in wavelet domain.
