Question

i want to the code of the Crack detection image processing using Matlab

Answer 1

%Image loading%

I=imread('two.jpg');

figure,imshow(I)

title('Original image')

%Adjust Image%

Istrech = imadjust(I,stretchlim(I));

figure,imshow(Istrech)

title('Contrast stretched image')

%Converting %

gray_s = rgb2gray(Istrech);

figure,imshow(Igray_s,[])

title('RGB to gray (contrast stretched) ')

%%Image segmentation by thresholding%

level = 0.08;

Ithres = im2bw(Igray_h,level);

figure,imshow(Ithres)

title('Segmented cracks')

BW = bwmorph(gradmag,'clean',10);

figure,imshow(BW)

title('Cleaned image')

BW = bwmorph(gradmag,'thin', inf);

figure,imshow(BW)

title('Thinned image')

BW = imfill(gradmag, 'holes')

figure,imshow(BW)

title('Filled image')

figure,imtool(BW1)

figure,imtool(I)

calibration_length=0.001;  

calibration_pixels=1000;

crack_pixel=35;

crack_length=(crack_pixel *calibration_length)/calibration_pixels;
