| 摘 要： | 港口目标的识别包括两个方面：识别港口轮廓和识别轮廓两侧的港口纹理，轮廓链码表示轮廓的走向及轮曲线的曲率，经过自适应平滑后由波变换的极大值检测得到角点，即大曲率点，港口轮廓的基元是一种连续四个角点的结构，基元的识别取决于这些角点有关的三个特征，这些特征只与角点的角度正负性质有关。

| Abstract: | 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. |
