图像边缘检测算法
(1)Robert算子边缘检测
(2)Sobel算子边缘检测
(3)Prewitt算子边缘检测
(4)LOG算子边缘检测
(5)Canny边缘检测
Matlab的实现。
其实还只是掉包侠,一点算法没有写
争取有空用openCV写一遍
I=imread('1.jpg'); I0=rgb2gray(I); subplot(231); imshow(I); BW1=edge(I0,'Roberts',0.16); subplot(232); imshow(BW1); title('Robert算子边缘检测') BW2=edge(I0,'Sobel',0.16); subplot(233); imshow(BW2); title('Sobel算子边缘检测') BW3=edge(I0,'Prewitt',0.16); subplot(234); imshow(BW3); title('Prewitt算子边缘检测'); BW4=edge(I0,'LOG',0.012); subplot(235); imshow(BW4); title('LOG算子边缘检测') BW5=edge(I0,'Canny',0.2); subplot(236); imshow(BW5); title('Canny算子边缘检测')
