數(shù)據(jù)壓縮導(dǎo)論

前言

Within the last decade the use of data compression has become ubiquitous. From mp3 players whose headphones seem to adorn the ears of most young (and some not so young) people, to cell phones, to DVDs, to digital television, data compression is an integral part of almost all information technology. This incorporation of compression into more and more of our lives also points to a certain degree of maturation of the technology. This maturity is reflected in the fact that there are fewer differences between this and the previous edition of this book than there were between the second and first editions. In the second edition we had added new techniques that had been developed since the first edition of this book came out. In this edition our purpose is more to include some important topics, such as audio compression, that had not been adequately covered in the second edition. During this time the field has not entirely stood still and we have tried to include information about new developments. We have added a new chapter on audio compression (including a description of the mp3 algorithm). We have added information on new standards such as the new video coding standard and the new facsimile standard. We have reorganized some of the material in the book, collecting together various lossless image compression techniques and standards into a single chapter, and we have updated a number of chapters, adding information that perhaps should have been there from the beginning.All this has yet again enlarged the book. However, the intent remains the same: to provide an introduction to the art or science of data compression. There is a tutorial description of most of the popular compression techniques followed by a description of how these techniques are used for image, speech, text, audio, and video compression.Given the pace of developments in this area, there are bound to be new ones that are not reflected in this book. In order to keep you informed of these developments, we will periodically provide updates at http://www.mkp.com.

內(nèi)容概要

本書是數(shù)據(jù)壓縮方面的經(jīng)典著作，介紹了各種類型的壓縮模式。書中首先介紹了基本壓縮方法(包括無損壓縮和有損壓縮)中涉及的數(shù)學(xué)知識(shí)，為常見的壓縮形式打牢了信息論基礎(chǔ)，然后從無損壓縮體制開始，依次講述了霍夫曼編碼、算術(shù)編碼以及字典編碼技術(shù)等，對于有損壓縮，還討論了使用量化的模式，描述了標(biāo)量、矢量以及微分編碼和分形壓縮技術(shù)，最后重點(diǎn)介紹了視頻加密。本書不但分析了各種壓縮模式及其優(yōu)缺點(diǎn)，而且還說明了它們最適合處理哪種內(nèi)容?！　”緯浅＿m合從事數(shù)據(jù)壓縮相關(guān)工作的專業(yè)技術(shù)人員、軟硬件工程師、學(xué)生等閱讀，數(shù)字圖書館、多媒體等領(lǐng)域的技術(shù)人員也可參考。

章節(jié)摘錄

插圖：Example 9.6.1:Suppose we have a source that can be modeled as a random variable taking values in the interval [-4，4] with more probability mass near the origin than away from it. We want to quantize this using the quantizer of Figure 9.3. Let us try to flatten out this distribution using the following compander, and then compare the companded quantization with straightforward uniform quantization. The compressor characteristic we will use is given by the following equation：
