基于九分块的颜色直方图图像检索算法

随着社会和科技的发展，人们对基于内容的图像检索的要求越来越高，但因研究起点较晚，技术还不是很成熟。文中就图像检索所用到颜色、纹理、形状、轮廓的基本颜色特征中比较重要的颜色特征为主要研究对象，从传统的基于全局颜色直方图及后来发展的一些改进的颜色直方图等思路出发，提出了一种基于九分块的颜色直方图方法，提高了图像检索的效率。

Image Retrieval Based on Nine Blocks and Color Features

With the social and technological development,the requirements of people's content-based image retrieval(CBIR) is higher and higher,but the starting point of research is later,and it is not very mature in technology.In this paper,the image retrieval using color,texture,shape,color characteristics of the basic outline of the more important for the color of the main characteristics of subjects,from the traditional color histogram and later an improved color histogram,a kind of color histogram based on nine pa...
