使用拼貼誤差直方圖的分形圖像檢索
Fractal Coding Based Image Retrieval Using Histogram of Collage Errors
-
摘要: 拼貼誤差是值域塊與最匹配的定義域塊相似性的一個度量,然而很多基于分形編碼參數(shù)的分形圖像檢索技術(shù)卻忽略了拼貼誤差。該文使用拼貼誤差直方圖作為檢索條件,來判定圖像的相似度。對有200多張紋理圖像的數(shù)據(jù)庫的實(shí)驗(yàn)顯示,該方法不僅減少了計算的復(fù)雜度,而且也有一定的檢索準(zhǔn)確率。

Abstract: Collage error is a quantitative measure of the similarity between range block and best-match domain block. However, it is neglected by many fractal-based image retrieval techniques. In this paper, a new fractal coding based indexing technique using histogram of collage errors is proposed. Experimental results on a database of more than 200 texture images show that the proposed method not only reduces computational complexities, but also enhances the retrieval rate. -
