摘要

提出了一种基于不可分二维多小波变换的小波图像表示、编码和压缩方法。这种方法的应用产生了二维小波函数和滤波器组，比传统的可分离变换更适合于二维信号(如图像)的编码。我们主要讨论多小波的设计。不可分离方法允许设计具有优选方向的二维多小波。给出了在施加矩消失要求时，多相矩阵分量必须满足的非线性约束。

Representation and coding of images with nonseparable two-dimensional wavelets

A method for wavelet image representation, coding and compression, using nonseparable two-dimensional (2D) multiwavelet transform, is presented. The application of this approach results in 2D wavelet functions and filter-banks that are more suitable for coding of two-dimensional signals, such as images, than the traditional separable transform. We deal mainly with the design of multiwavelets. The nonseparable approach permits the design of 2D multiwavelets with preferred orientations. We also present the nonlinear constraints on the polyphase matrix components which must be satisfied while imposing the requirement of vanishing moments.
