摘要: 本文用形心到外轮廓的距离序列表示形状,从而将二维的形状分析问题转化成较简单的 一维波形曲线的分析问题,对于这种波形曲线的识别,提出了一种特征区域的局部匹配识别 算法.实验证明,本文方法具有较高的识别率,且该算法是平移、旋转和比例变化不变的.Abstract: Target shapes are represented by the sequence of distances between the centroid and contour in this paper. Therefore, the problem of two-dimensional target shape analysis is simplified as the one of one-dimensional waveform analysis. And an algorithm of local match recognition is proposed. Experiments show that the algorithm has high correct recognition ratio, and is invariant to translation, rotation and scale.
