摘　　要：本文介绍了一种基于纹理特征中心加权的图像检索算法.计算差分矩阵进行纹理的相似度比较,并且根据图像中心的重要性,对图像不同像素的差分值采用不同的加权系数,越靠近图像中心加权系数越大.最后,与差分直方图进行比较,实验表明,本文算法具有比较好的检索结果.This paper introduces an image retrieval algorithm based on texture features and compare the similarity by difference matrix.According to the importance of the image centre,the different feature weights are adopted in the different difference.Feature has more high weight when close to the image center.Finally,comparing with difference histogram method,the experiment results show that the proposed algorithm has better retrieval results.
