摘　　要：为实现形态滤波在实时数字信号系统中的应用,通过对一维形态滤波算法理论分析,推导出可用于实时运算的表达方式.对结构元素进行讨论,揭示了结构元素在实时信号处理中选取的一般规律.通过实验实现对数字信号的实时滤波,验证了结构元素的不同选取与滤波效果的关系.此方法具有处理速度快,滤波效果好,通用性高的特点,可应用于多种信号的实时处理.To meet the need of application of morphological filtering in real-time signal processing, the paper has analyzed one-dimensional morphological filtering algorithm and given the representation for real-time computing. The rules for real-time signal filtering choosing deferent structural elements have been revealed by discussing structural elements. And the link between structural elements choosing and filtering effect has been found by experiment. The method has a high processing speed with high filtering efficiency, common currency for different kinds of signals in real-time processing.
