摘    要:Aibing Rao提出的环形颜色直方图加入了图像颜色的空间信息,但仍存在一些问题.本文在环形颜色直方图的基础上提出如下改进:采用具有视觉一致性的HSV颜色空间代替传统的RGB颜色空间;对不同的颜色通道给予不同的量化级数,对H通道给予更多的量化级数,并将H,S,V 3个分量进行非等间隔的量化;将H,S,V3个分量加权求和构造出环形颜色直方图的行,其中色调H的权重大于饱和度S和亮度V的权重.实验验证了改进算法的有效性.

Abstract:The circular color histogram which put forward by Aibing Rao contained the image space information.The improvement algorithm is: to adopt HSV color space which has the visual uniform,gives the different quantification progression to the different color channel,and H,S,V three components carries on no laddered quantification,H,S,V three components weighting summation composes the row of the circular color histogram construction.The experiment has confirmed the improvement algorithm validity.
Keywords:content beased image retrival   color histogram   circular color histogram   color space
