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。
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 a (?)alysis. And an algorithm of local match recognition is proposed. Experiments show that the algorithm has high correct recognition ra(?)io, and is invariant to translation, rotation and scale.
