【摘要】 提出了一种综合颜色和纹理特征的图像检索算法。使用圆环法分割图像所提取的颜色特征,不仅包含了图像的空间信息、突出了图像的感兴趣区域,而且消除了固定分块法对图像旋转比较敏感的缺点。采用改进的共生矩阵算法提取纹理特征。最后对颜色和纹理特征进行综合。实验结果表明,提出的综合算法具有更高的查准率。更多还原

【Abstract】 A new method for image retrieval combining color with texture features is proposed.Firstly,the color features which are extracted by the ring segmentation method,not only include the spatial information of images and emphasize the region of interest,but also overcome the shortcoming of the fixed sub-block method being sensitive to image rotation.Then,texture features are extracted by the improved symbiotic matrix algorithm. Finally,the color features are combined with the texture features.The experimental results show that the proposed algorithm has better precision.更多还原
