摘要: | 本論文完成一個符合JBIG壓縮標準的系統。JBIG採用特別的預測方法及適 應性算數編碼系統,並且提供漸進式編碼的功能,使得接收端使用者,可 以先預覽低解析度的全圖,以決定是否傳送後續資料。本系統除了提供標 準的JBIG編碼、解碼功能外,並提供漸進式的全圖瀏覽器。 In the thesis, we implement a software system that follows the compressionstandard JBIG. The JBIG standard adopts special prediction methods and use the adaptive arithmetic coding technology as its entropy coder. It also provides a progressive coding function. The remote receiver can view the low resolution whole image soon. He can determine whether the following image data shall be sent or not. In this system, we provide normative JBIG encoder/decoder functions. Besides, we design a progressive browser to view progressive images. |
