We describe the analysis and identification of a network of surface cracks on the basis of processing of digital images. A three-dimensional analysis has been performed by a combination of two measured parameters: the length and depth of a crack. On the basis of processing of a limited number of data, the system can analyze cracking of the surface of a roll of a continuous slab-casting machine. Theoretical prerequisites and experimental results are presented.
