Abstract: This article proposes essential color of color feature and gradation paragenesis matrix of the texture characteristic，as well as the correlation feedback technology carried on together the retrieval.This article uses the correlation feedback technology to adjust the feature coefficient of color and texture and weight value of the block of this two feature.The experimental result indicates that，this method has a higher accuracy，and has the better retrieval effect.

摘要： 提出了将颜色特征中的分块主色法，纹理特征中的分块灰度共生矩阵以及相关反馈技术相结合来共同进行检索，并采用相关反馈技术通过更新权值的方法来调整图像颜色、纹理特征系数以及对应于这两种特征的图像各分块的权值。实验结果表明，该方法具有较高的准确性，并且具有较好的检索效果。
