最优的阶梯型边缘检测算法(canny边缘检测)
1.Canny边缘检测基本原理
(1)图象边缘检测必须满足两个条件:一能有效地抑制噪声;二必须尽量精确确定边缘的位置。
(2)根据对信噪比与定位乘积进行测度,得到最优化逼近算子。这就是Canny边缘检测算子。
(3)类似与Marr(LoG)边缘检测方法,也属于先平滑后求导数的方法。
2.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;

根据CNNAY算法的4个步骤
1. 用高斯滤波器平滑图像;(图像去噪)
2. 用一阶偏导有限差分计算梯度幅值和方向;(特征增强)
3. 对梯度幅值进行非极大值抑制 ;(边缘检测)
4. 用双阈值算法检测和连接边缘。(形态学处理)
