Abstract
This paper analyzes the effect of changes in the key parameters of an algorithm for identifying cracks in images of rolls of continuous casting machines. The effects of the background threshold of binary conversion and the filter kernel size on the total error of calculations of geometric characteristics of cracks are considered. The range of crack lengths for which the developed algorithm is suitable is calculated based on experimental data.
