Tree code decoding 樹碼譯碼
We have done the following work : we have designed wavelet transform and zero - tree coding based still image compressing / decompressing programs in matlab environment 課題進行了以下的工作:編制出了在matlab下運行的基于小波分解和零樹編碼的單幀圖像壓縮解壓程序。
The authors present an improved zero - tree coding method through researching on the image margin , which is an adaptive zero - tree coding method based on integral wavelet transform 在研究了圖像的重要特征圖像邊緣的基礎上,提出了一種改進的零樹編碼方法基于整數小波變換的分塊自適應零樹編碼方法。
The purpose of our research is to study the data compression coding method of still image . in this paper , an improved zero - tree coding method based on wavelet transform is proposed . with the related experience , it was proved effective 本文就靜態圖像數據壓縮編碼方法進行了研究,提出了一種改進的基于小波變換的零樹編碼方法,通過實驗證明了此方法的有效性。
