摘要
Abstract
To improve the affine invariance of features of shape, the chord location matrix algorithm is proposed. The chords location can be determined by affine invariance ratio of the closed areas. The chords location in all directions and sorting information of chords with different length on same position can construct chord location matrix as the feature vectors. The Dynamic Space Warping(DSW) algorithm proposed is used as similarity measure. Experimental results show that the approach is robust to affine transformation.关键词
