This paper describes a method that tries to improve the accuracy of a machine vision algorithm for frayed edge detection in coldrolled electrical grain oriented steel plate with usage of the Singular Value Decomposition. The algorithm being improved is based on preprocessing the image with the Multi Scale Retinex algorithm, application of the Sobel filter(More)
This paper proposes method for solving steel alloying problem using evolution algorithms SOMA and differential evolution. Both algorithms belong to the family of the evolution algorithms but the main ideas of these algorithms are different. In differential evolution new offspring is created during the evolution, the individuals are crossed and mutated,(More)
