摘　　要：形态学滤波作为一种新型的非线性滤波方法已被广泛应用到边缘提取、抑制噪声等图像处理领域。形态结构元的选择作为形态学滤波的最关键问题一直以来是形态学研究的热点之一,通过对顺序形态学极值滤波运算的研究,提出了一种基于复合极值滤波的最佳结构元尺度自适应确定算法。实验结果表明,该方法能快速、准确地确定结构元的尺度大小,具有很好的形态滤波效果。As a new type of non-linear filtering method, morphology filter has been widely applied in image processing such as edge extraction and noise removing etc. The selection of morphological structuring element as the most critical issue of morphology filter has been a hot one of the morphological research, the paper proposes an adaptive approach based on compound extreme filter to define optional size of structure element, which depends on the research of extreme computing of order morphology. The experimental results show that the method can select the scale of structuring element exactly, and have good effect on morphology filter.
