Abstract

To solve the problem of object recognition with geometrical distortions, it is proposed to use central moments of inertia of edge line segments occurred in the sector while radial-circle scanning of objects. The scanning center is located in the central moments of inertia of each observed object. Such a scanning ensures scale invariance of size of the feature vector and robustness of recognition algorithms. This feature vector is used to obtain an algorithm of simultaneous recognition and estimation of geometrical distortion parameters, and a correlation recognition algorithm. Both of them are very robust.
