摘要：
The recognition method of the harbor target is presented. There are two aspects in the recognition. One is the recognition of the harbor contour, the other is the recognition of the texture of the harbor area on one side of the contour. The chain code of the contour represents the orientation and the curvature of the contour, and the control points are detected by the extrema of the wavelet transform after adaptive smoothing. The primitive of the harbor contour is some structure of successive control points. The primitive is recognized by three features related to these points, which are scale-and rotation-invariant.
