VERTEX DETECTION ALGORITHM IN IMAGE PROCESSING BASED O N BINARY IMAGE CONTOUR APPROXIMATION

The salient image feature detection task is one of the central problem of image processing. This paper presents the improvement of the developed by the author the vertex detection algorithm in image processing based on approximation of binary image contour by vector. For example, new rules on approximation with given accuracy of binary image contour by directed segments were developed to more accurately and quickly effective detection of the vertex. Brief emphasis on main image salient feature detection algorithms provided. The comparative evaluation of these algorithms carried out.
