摘　　要：在环形颜色直方图基础上采用具有视觉一致性的颜色空间——HSV,并把各通道分别进行非等间隔量化,采用各通道向量加权的形式把各通道组合为一个特征向量作为环形颜色直方图的颜色值,最后采用扩展的直方图交算法进行相似性匹配。实验验证了这种方法的有效性。The circular color histogram to adopt HSV color space is improved which has the visual uniform, gives the different quantification progression to the different color channel, and H, S, V three components carry on no laddered quantification, H, S, V three components weighting summation composes the row of the circular color histogram construction. Finally the expanded histogram intersection algorithm for matching similarity is used. The experiment has confirmed the improvement algorithm validity.
