Digital Signal Processing Technology Based on Dilation and Erosion Algorithm

针对工程中数据信号的质量评价,分类等算法复杂,动态性不足的问题,本文采用数学形态学上的膨胀与腐蚀算法简化了质量评价问题,同时给出了动态引入判定期约束信号参与运算的通用方法。该方法具有通用性,在简化主体信号判定过程的同时,可以动态改变约束条件及运算的方法,提高整体评价结果完整性、准确性。

In order to solve the problem of algorithm complexity of quality evaluation and classification of engineering data signals,and lack of dynamic,this paper adopts the dilation and erosion algorithm of mathematical morphological to simplify the quality evaluation,and gives the general method which constraints signal involved in computing by dynamicly intro-duce determation phase.This method has generality,and it not only can simplify the process of the main signal determination,but also can dynamically change constraint conditions and operational method,and improve the com-pleteness and accuracy of the overall estimated results.
