A., Registration Date 22-07-2005 Organization Karpenko Physico-Mechanical Institute of the National Academy of Sciences of Ukraine popup.description2 The profile image of external thread is the subject of inquiry of given work. The aim is development of mathematical models of deterioration objects of constructional element at the process of exploitation on the basis of information technologies of image processing. The methods of investigation are mathematical and computer simulationThe advisability of shadow method usage for object form obtaining and application of relative local contrast is shown. More sensitive method in comparison with known ones for edge extraction is developed. The iterative technique for decreasing of noise influence on image on the basis of fuzzy logic rules. The information technology for determination of coordinates of vertex on profile of external thread’s tooth on the basis of Hough transform is constructed. On the basis of developed algorithms for approximation of functions by Chebyshov balanced splines the program package for the one-variable function approximation was created.
