digital image compression coding

基本解释

The paper introduces the reason of image compression and digital image compression and coding .
本文介紹了圖像壓縮的原因及數字圖像壓縮編碼。
By still image compression coding technique, the color digital watermark is encoded into a series of binary ID numbers for watermarking.
利用靜態圖像的壓縮編碼技術，將彩色數字水印編碼爲一系列二值ID數字，以實現水印的嵌入。
The Method based on the DCT transformation has been the center technology for most of the digital image and video coding standards, since it features on good de-correlation and energy compression.
基於分塊DCT變換的編碼方法，由於具有良好的去相關性和能量壓縮特性，已經成爲現有大多數圖像和眡頻編碼標準的核心技術。
