| 摘 要： | 为了消除基于颜色的图像检索在颜色空间分布描述方向的不足,提出一种新的基于颜色的检索方法。引入颜色转移矩阵描述颜色的空间分布,再结合颜色直方图和颜色转移矩阵进行复合图像检索。同时通过矢量量化方法量化图像颜色得到颜色直方图和颜色转移矩阵,实现了在压缩领域进行图像检索,减少了额外计算负担。实验表明,该方法能有效提高检索效率和精度。

| Abstract: | Color image retrieval is not good at describing the spatial distribution of color,in order to eliminate this disadvantage,we present a new color retrieval method.The color transfer matrix method is introduced to describe the spatial distribution of color,so color transfer moment combined with color histogram for color image retrieval.Color histogram and color transfer moment by vector quantization method to quantify the image of color.This method achieved image retrieval in the compressed field,and reduced the additional computational burden.Experiments show that this method can effectively improve search efficiency and accuracy. |
