What that means is a horizontal hairline crack could be 1 pixel in width whereas medium and extended could be 3 pixels and 5 pixels wide, respectively

Hi!
I need matlab programming services. I am trying to create a code that can detect different types of cracks on concrete surfaces. horizontal, vertical and diagonal cracks. These three cracks are further subcategorized into hairline, medium and extended cracks. What that means is a horizontal hairline crack could be 1 pixel in width whereas medium and extended could be 3 pixels and 5 pixels wide, respectively (this is just an example, their actual width in terms of pixels will be provided later). Once any of these crack is detected on the concrete surface, a simple evaluation function is used to determine the rating of the surface. Also, a line should be drawn over the identified crack on the image.
I cannot use predictive identification because I do not have enough pictures. So these will need to be coded by usimg functions and commands. A sample of a crack is attached.
Kindly let me know if the task is not clear. I can explain via an online meeting if necessary.
Thanks!
