X樹圖像編碼

The X-tree image coding

  • 摘要: 該文提出一種新的小波圖像編碼結(jié)構(gòu)X樹。X樹是除根節(jié)點外其余的節(jié)點均為0的四叉樹,它是零樹的一種推廣。在X樹的基礎(chǔ)上,文中提出了普通X樹圖像編碼和嵌入式X樹圖像編碼兩種編碼方案,實驗表明該文提出的方案的編碼效率明顯高于零樹(EZW)和棧-游程(Stack-run)編碼。
    Abstract: This paper presents a new scheme of wavelet image coding, X-tree. An X-tree is a spatial hierarchical tree whose all nodes are 0 except the root node. It is the generalization of the zero tree. Based on the X-tree scheme, two new coding algorithms, the embedded X-tree approach and the general X-tree approach are proposed in the paper. Experimental results show that the coding efficiency of the proposed algorithms are obviously higher than those of the stack-run and the EZW algorithms.
