广义门阈分解理论

A Generalized Threshold Decomposition

基于传统中值滤波的分析和实现方法，进一步导出了广义门阈分解ＧＴＤ（ＧｅｎｅｒａｌｉｚｅｄＴｈｒｅｓｈｏｌｄＤｅｃｏｍｐｏｓｉｔｉｏｎ）理论，研究了有关性质和实现问题。其效果不仅大大地简化了理论分析和硬件实现，而且也进一步完善了非线性滤波的有关理论。

In this paper, a new technique, the generalized shresholod decomposition(GTD) for the analysis and implementation of medlian filters is introduced. This technique not only is belter than the original method of filters but also approaches the completion of the nonlinear filtering theory in the analysis and VLSI realizetion.
