An image retrieval method of connecting integral and local color character
Jing Zhao · Microcomputer & its Applications · 2009
For solving these problems that the conventional color histogram can't reflect the position of the point and the local detail of the image,a new retrieval method which integrates the local character containing color and position into the whole character is presented in this paper. Firstly,the image is divided into annular region by annular division,and then calculates the local color character. And then the similarity of the image is defined as the combination of the similarity of the integer and the similarity of the annular blocks to reflect the recognition process by people. The experimental result on real-world images indicates that the proposed approach reflecting the spatial information of colors and the local detail of the image is better than the conventional retrieval method based on color histogram in an accurate and complete survey.
