This chapter set forth the definition and the character of wavelet transform , binary wavelet and wavelet frame . the kernel of wavelet transform , i . e . multi - resolution analysis , the decomposition reconstruction method of sign and image multi - resolution , wavelet feature in the image process are all discussed . the chapter three is about texture image segmentation and texture analysis . the definition of texture and normal texture segmentation method are introduced 第二章为小波变换理论，从信号与图象处理的角度引进小波变化的定义，介绍了小波产生的思想以及基本理论，给出了小波变换、二进小波、小波标架的定义极其性质，对小波变换的核心? ?多分辨率分析进行讨论，对基于小波变换的信号与图象多分辨率分解与重构方法进行了介绍，并给出了图象处理中所表现的小波特性。
