摘　　要：针对不同形状结构元素对颗粒物图像边缘的不同感应能力,小尺度的结构元素去噪声能力弱但能较好地检测到边缘细节,以及大尺度的结构元素检测的边缘较粗但去除噪声能力强等特点,提出了一种多尺度多结构元素的数学形态学颗粒物图像边缘检测方法,同时采用不同尺度下的多个结构元素的边缘检测算子,实现颗粒物图像的各种边缘检测。实验结果表明,这种边缘检测方法能有效地滤除噪声,且抗干扰能力较强。Different structural elements have different detecting abilities to the image edges. The small - scale structural elements have better edge details but less denoising ability;the large - scale structural elements are equipped for higher denoising ability but rougher image edges. A mathematical morphology edge detection method was put forward with multi - scale and multi - structural elements. It can achieve a variety of particle image edge detection with different scales structural elements. Experiments show that the edge detection method can filter the noises effectively;and it has stronger ability to resist disturbance than others.
