Khalid Sayood

美國內布拉斯加大學工程學教授，分彆於1977年和1979年獲得羅徹斯特大學電氣工程學理學學士和理學碩士學位，並於1982年獲得得剋薩斯州農工大學電氣工程學博士學位。他的主要研究方嚮包括數據壓縮、信源信道聯閤編碼和生物信息學。

Each edition of "Introduction to Data Compression" has widely been considered the best introduction and reference text on the art and science of data compression, and the third edition continues in this tradition. Data compression techniques and technology are ever-evolving with new applications in image, speech, text, audio, and video. The third edition includes all the cutting edge updates the reader will need during the work day and in class. Khalid Sayood provides an extensive introduction to the theory underlying today's compression techniques with detailed instruction for their applications using several examples to explain the concepts. Encompassing the entire field of data compression "Introduction to Data Compression", includes lossless and lossy compression, Huffman coding, arithmetic coding, dictionary techniques, context based compression, scalar and vector quantization. Khalid Sayood provides a working knowledge of data compression, giving the reader the tools to develop a complete and concise compression package upon completion of his book. New content is added on the topic of audio compression including a description of the mp3 algorithm. New video coding standard and new facsimile standard explained. Completely explains established and emerging standards in depth including JPEG 2000, JPEG-LS, MPEG-2, Group 3 and 4 faxes, JBIG 2, ADPCM, LPC, CELP, and MELP. Source code provided via companion web site that gives readers the opportunity to build their own algorithms, choose and implement techniques in their own applications.
