digital image compression coding

基本解釋

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(shù)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(tài)圖像的壓縮編碼技術(shù)，將彩色數(shù)字水印編碼為一系列二值ID數(shù)字，以實(shí)現(xiàn)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.
基于分塊DCT變換的編碼方法，由于具有良好的去相關(guān)性和能量壓縮特性，已經(jīng)成為現(xiàn)有大多數(shù)圖像和視頻編碼標(biāo)準(zhǔn)的核心技術(shù)。
