| 摘 要： | 使用颜色直方图进行图像检索是图像检索的常用方法，但是传统颜色直方图检索容易丢失空间信息，从而影响图像检索的查全率和查准率.针对这一问题，提出一种改进算法，该算法首先进行图像分块，然后通过对各分块颜色直方图加权的方法进行检索.实验证明，该算法可以提高图像检索结果的查全率和查准率.

| Abstract: | The use of color histogram is a common method for image retrieval,since conventional color histogram retrieval method is prone to lose the spatial information of colors,thus affecting both the recall and the precision.A new image retrieval algorithm is proposed in this paper.According to the method,an image is cut into sub-blacks first;then the retrieval is performed by the weighted method of sub-block’s color histogram.Experimental results show that both the recall and the precision are improved effectively. |
