提出了一种基于形态学的非线性小波分析方法,并将这种形态小波分析方法应用于图象编码上.与一般的小波分解方法不同的是,该形态小波分解采用非线性方法,分解结果中图象特征更明显,图象编码压缩比更高,解码出的图象更加清晰;同时由于形态学是基于Minkowski加减基本操作并应用最大最小运算来实现,分解运算简单,速度快. A morphological nonlinear wavelet analysis method is proposed, and this morphological wavelet analysis method is applied to image coding.Compared with the general wavelet decomposition method, this morphological wavelet decomposition adopts a non-linear method to decompose the result The image features are more obvious, the image compression ratio is higher, and the decoded image is more clear. Meanwhile, the morphology is based on Minkowski addition and subtraction basic operations and the application of maximum and minimum operations, the decomposition operation is simple and fast.
