煤矸石二值图像的Roberts快速边缘检测法

A Fast Edge Detection Roberts Algorithm of Coal Gangue Binary Image

根据煤矸石图像处理技术的特点,研究了煤矸石的轮廓提取与边缘加强,分析了Roberts边缘检测算子的特点,提出了针对煤矸石二值图像快速边缘检测的改进Roberts算法,取得了良好的快速性和较好的检测效果。

According to the characteristics of binary image in the automatic separation system of coal and gangues, the contour extraction and edge enhancement of coal gangues are investigated, the feature of traditional Roberts edge detection algorithm is analyzed. Then a novel fast edge detection algorithm of binary image is proposed to improve the Roberts operator for coal gangue image processing. The experiment result reveals that the proposed algorithm is efficient and practicable.
