图象信号多分辨率分解结构的研究

Study on splitting structure for multi resolution representation of image signals

从兼容应用的角度，研究了图象信号子带分解的两种结构。指出等级分解可自然地满足各级图象格式的兼容应用要求，并且分解灵活，而并行分解则对应不同的信号格式要设计不同的综合滤波器组。

Based on subband splitting,study on splitting structure of image signals is described in this paper.Hierarchical splitting makes different resolution formats compatible naturally.Parallel splitting reqires different synthesis filter banks for image formats with different resolution.
