一种分形域基于内容的图像检索方法

CONTENT-BASED IMAGE RETRIEVAL IN FRACTAL DOMAIN

基于内容的图像检索是多媒体、网络通信及计算机等应用研究领域的一项关键技术。该文提出了一种在分形压缩域直接进行基于内容的图像检索方法。该方法不需要对查询图像进行分形变换,因此可以提高检索速度,降低检索复杂度。仿真结果表明,使用该文提出的方法,能够有效地进行分形域基于内容的图像检索,比较大幅度地降低了检索时间,优于试验中其他3种方法。

Content-based image retrieval is a key technique in multimedia, network communication and computer applications, etc. In this paper, a content-based image retrieval method is proposed, which can be executed in fractal domain and does not need to do fractal coding of the iconic image. Thus the retrieval complexity and retrieval time can be reduced greatly. Experimental results have shown that the method proposed is very effective and better than the other three retrieval methods.
