Dear Ivan,

I've trouble determining what are cracks and what is noise in your picture.
I've put together a small macro that may be a base for you to get started.
Note that this requires Fiji (as it uses the Analyze Skeleton plugin)

setAutoThreshold("Default dark");
setThreshold(95, 116);
setOption("BlackBackground", false);
run("Convert to Mask");
run("Skeletonize");
run("Analyze Skeleton (2D/3D)", "prune=none show");

Regards,

Paul
