MATLAB裂缝检测识别

MATLAB代码

%%读取图片
srcImg=imread('C:\Users\HP\Desktop\001.jpg');
subplot(331);imshow(srcImg);
title('原始图像');
%%区域增强
adjImg=imadjust(srcImg,[0.25,0.60],[0,1]);
subplot(332);imshow(adjImg);
title('区域增强');
%%矫正不均匀亮度
se=strel('disk',5);
imbImg=imbothat(adjImg,se);
subplot(333);imshow(adjImg);
title('底帽变换矫正不均匀亮度');
%%高斯去噪
H = fspecial('gaussian',3,3);
filImg = imfilter(imbImg,H,'replicate');
subplot(334),imshow(filImg);
title('滤波去噪');
%%裂缝区域重构
bwImgBig=im2bw(filImg,90/255);
subplot(335),imshow(bwImgBig);
title('大阈值');
bwImgSmall=im2bw(filImg,80/255);
subplot(336),imshow(bwImgSmall);
title('小阈值');
%%去除图像边框
recImg=imreconstruct(bwImgSmall,bwImgBig);
[m,n]=size(recImg);
recImg(1,1:n)=0;
recImg(m,1:n)=0;
recImg(1:m,1)=0;
recImg(1:m,n)=0;
subplot(337),imshow(recImg);
title('去除图像边框干扰');
%%去除小于100的区域
recImg=bwareaopen(recImg,100);
subplot(338),imshow(recImg);
title('去除小于100的区域');
subplot(339),imshow(recImg);
title('裂缝检测提取结果');
