基于小波变换的彩色自然图像数据库自动检索

AUTOMATIC RETRIEVAL OF COLORED NATURAL IMAGE DATABASE BASED ON WAVELET 

针对彩色自然图像数据库,提出了一种新的基于小波帧包变换的自动检索方法。该方法有效结合了纹理信息和颜色信息,克服了以往方法将低层特征孤立起来的缺陷,同时,图像检索过程以渐进的方式进行.本文方法无论在检索效率及检索准确率上都能获得好的效果.

This paper proposes a novel wavelet frame packet analysis approach for automatic retrieval of images in a colored natural image database. The approach effectively combines both the texture and color information and retrieve images in a progressive way. It can produce good performance in terms of both retrieval efficiency and retrieval effectiveness.
