| 摘 要： | 基于内容的图像检索中,颜色特征已得到广泛应用.传统颜色直方图检索方法不能体现图像空间信息,提出并实现了一种改进方法.进一步分析了具有相关颜色的像素之间在空间分布上的差异,用其在图像中形成的最大连通区域面积代替传统直方图中使用的数量总和指标,从而能够间接反映色彩的空间分布特征,提高检索质量,并保持了颜色直方图原有的旋转、平移不变性.

| Abstract: | In content-based image retrieval,color features are widely used.An improved method is proposed to overcome the problem that the traditional color histogram method does not take the spatial information of colors into account.The presented method analyzes the spatial distribution difference among the pixels of correlative color and replaces total amount of pixels used in traditional histogram with the maximum connected region area.Thus,spatial distribution feature of color is reflected indirectly,while rotation and translation invariance of traditional color histogram are kept. |

| Keywords: | image retrieval maximum connected region area histogram connected region of color |
