用来产生图像边缘增强效果的运算单元。取2×2或3×3的矩阵。当取2×2矩阵时,可增强被该运算单元所覆盖区域的左上角像素与周围像素间的灰度差,当取3×3矩阵时被增强的像素则位于所覆盖区域的中心。通常使用的边缘算子有离散梯度算子、Roberts算子、Laplacian算子和Sobel算子等。
在利用改进的SUSAN算子进行亚像素角点检测时,综合应用了索贝尔边缘算子、灰度平方重心法等方法。
Sobel operator and gray square centrobaric arithmetic were synthesized with the improved SUSAN operator in subpixel corner detection.
然后利用微观检测算子检测出微小型零件的边缘点;
The second step is to detect the edge point by microcosmic operator.
