摘　　要：为了简单、准确定义图像的颜色特征,提出了基于区域块的颜色直方图技术。将目标集中在图像的中间区域,按照金字塔结构对图像分区并构建分区颜色直方图;相同区域内容在不同层中描述,从而可以在一定程度上解决普通直方图很难表达空间信息问题。In order to describe the features to a color image more simply and accurately, a region-based color histogram approach is pro- posed. It focuses its attention on the center of an image, segments an image into several blocks with pyramid data structure, and builds an integrated color histogram composed with subregion color histograms. This integrated color histogram overcomes the disadvantage of simple global color histogram.
