In this thesis, an improved method is proposed to overcome the problem that the circular color histogram method does not take the spatial information of colors into account , combines spatial distribution information with image color features. The presented method adopt color space which has the visual uniform , three components carries on no laddered quantification, three components weighting summation composes the row of the circular color histogram construction, and improves retrieval quality, while rotation and translation invariance of color histogram are kept.

针对颜色直方图对图像的空间信息表现不够的问题，本文提出并实现了环形颜色直方图的改进方法，将图像颜色特征和颜色的空间分布信息相结合，采用具有视觉一致性的颜色空间，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，提高了检索质量，并保持了原有算法的有效性和旋转不变性。
