anny边缘检测算子是John F. Canny于 1986 年开发出来的一个多级边缘检测算法。
Canny边缘检测算法:
step1:用高斯滤波器平滑图象;
step2:用一阶偏导的有限差分来计算梯度的幅值和方向;
step3:对梯度幅值进行非极大值抑制;
step4:用双阈值算法检测和连接边缘。-anny edge detection operator is John F. Canny developed in 1986 out of a multi-level edge detection algorithm. Canny edge detection algorithm: step1: Gaussian smoothing filter image step2: first-order finite difference to calculate partial derivatives of the magnitude and direction of the gradient step3: the gradient magnitude non-maxima suppression step4: use dual-threshold algorithm for detecting and connecting edges.
