Local Match Recognition of Discrete Shape
离散形状的特征区域匹配识别

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.
