Paper Abstract

The recognition method for the harbor contour is presented in this paper. The chain code of the contour represents the orientation and the curvature of the contour, and from it the control points are detected by the extra of wavelet transform. The primitive of the harbor contour is composed of four consecutive control points satisfying certain criteria. Three features of the primitive, which are scale- and rotation- invariant, and the deduced recognition rule, with the form of shape energy, are described in the paper.
