A New Method of Fractal IFS Image Database Retrieval Combining Discriminant Function

摘要

摘要: 该文提出一种分形编码的图像比对搜索方法,即把迭代函数系可反映图像的拓扑特性,用于图像的储存和检索.而图像经过分形编码后,得到大量资料,需要一个有效的方法进行检索,文中根据Fisher判别函数来判定图像相似度.实验结果表明,图像比对搜索引擎能准确找出查询图像的相似图像外,还证实本方法对图像有一定的容错性能,能有效地提高图像比对搜索引擎在实际应用中的可适性。

Abstract: In this paper, a new method of image compare search engine for fractal coding is proposed, namely using image topology characteristic of Iterative Function System (IFS) and applying to image deposit and retrieval. However, the image produces a lot of data by fractal coding and needs an effective method to retrieval, so this paper is based on Fisher discriminant function to estimate images similarity. Experiment shows image compare search engine can get exactly similar image of query image, it also has been testified better for tolerate-error and can effectively improve adaptivity in practice of image compare search engine.
