An Image Retrieval Method in JPEG2000 Compressed Domain
-
摘要: 該文首先分析JPEG2000壓縮域數(shù)據(jù)結(jié)構(gòu),在此基礎(chǔ)上,提出信息樹的概念,并提出一種新的樹距離度量方法。接著提出一種JPEG2000壓縮域圖像檢索方法,實驗結(jié)果表明,該文方法能取得明顯的檢索效果。

Abstract: The data structure in JPEG2000 compressed domain is firstly analyzed. The concept of information tree and a novel tree-distance measurement are then proposed. Finally, a new image retrieval method in JPEG2000 compressed domain is proposed. Experimental results show its potential in the research of compressed domain image retrieval techniques. -
