利用局部累加直方图进行彩色图象检索

在分析利用累加直方图对彩色图象进行检索的基础上首次引入了局部累加直方图以提高检索效率。本文还对ＨＳＶ（即色度、饱和度、亮度）空间中颜色的相似分布进行了研究，提出了一种新的相似色区间划分方法。基于以上研究，本文提出了４种新的利用局部累加直方图和新的相似色区间划分方法的图象检索算法。对真实图象检索的实验结果表明，这４种新算法的性能均远优于一般的累加直方图法。

Color Image Retrieval Using Local Accumulative Histogram

Along with the analysis of color image retrieval using accumulative histogram, the concept of local accumulative histogram is first introduced in this paper. In addition, the distribution of similar colors in HSV space is studied and a new dividing method for similar color regions is obtained. Based on these studies, four new algorithms of image retrieval using local accumulative histogram and new dividing method for similar color regions are proposed. The performances of these new algorithms are proved much better than the algorithms using accumulative histogram as shown by the retrieval experiments with real images.
