Algorithms are based on piecewise-linear approximation of the cumulative histogram of the image. An algorithm for constructing a visual image of a distributed cumulative histogram has been developed. An algorithm for clustering K-means for grouping data and pixels of images has been developed. The algorithm is applied to multilevel image segmentation. An algorithm for pixel-by-pixel subtraction of intensity and logical comparison of images has been developed. All algorithms are programmed and applied to images of different types: metal and material surfaces, printed circuit boards, etc. Programs allow you to determine the location of defects on surfaces and determine their intensity. In printed circuit boards, they allow you to identify defects in the connection and incorrect coverage of routes and contacts. Product Description popup.authors popup.nrat_date 2022-03-09 Close
