extracting area of cracks from image
Dear all, I wrote this code to extract cracks from a tomography image. I tried many ways to remove the background and enhance the colors for better crack extraction, but some cracks are still missing. Can anyone help me improve the code?

[centers,radii] = imfindcircles(A,[500 650],Sensitivity=0.95);
mask = circles2mask(centers,radii,size(A));
new_image = A;
new_image(~mask) = nan;

Iflatfield = imflatfield(new_image,sigma);
