商品描述

This book explains the stages necessary to create a wavelet compression system for images and describes state-of-the-art systems used in image compression standards and current research. It starts with a high level discussion of the properties of the wavelet transform, especially the decomposition into multi-resolution subbands. It continues with an exposition of the null-zone, uniform quantization used in most subband coding systems and the optimal allocation of bitrate to the different subbands. Then the image compression systems of the FBI Fingerprint Compression Standard and the JPEG2000 Standard are described in detail. Following that, the set partitioning coders SPECK and SPIHT, and EZW are explained in detail and compared via a fictitious wavelet transform in actions and number of bits coded in a single pass in the top bit plane. The presentation teaches that, besides producing efficient compression, these coding systems, except for the FBI Standard, are capable of writing bit streams that have attributes of rate scalability, resolution scalability, and random access decoding. Many diagrams and tables accompany the text to aid understanding. The book is generous in pointing out references and resources to help the reader who wishes to expand his knowledge, know the origins of the methods, or find resources for running the various algorithms or building his own coding system.

商品描述(中文翻譯)

本書解釋了創建影像小波壓縮系統所需的各個階段,並描述了在影像壓縮標準和當前研究中使用的最先進系統。書中首先對小波變換的特性進行高層次的討論,特別是多解析度子帶的分解。接著,介紹了在大多數子帶編碼系統中使用的零區域(null-zone)和均勻量化(uniform quantization),以及對不同子帶的比特率最佳分配。然後,詳細描述了FBI指紋壓縮標準和JPEG2000標準的影像壓縮系統。隨後,詳細解釋了集合分區編碼器SPECK、SPIHT和EZW,並通過虛構的小波變換進行比較,分析在頂位平面中單次傳輸編碼的位元數。這部分內容教導讀者,除了產生高效的壓縮外,這些編碼系統(除了FBI標準)還能生成具有速率可擴展性、解析度可擴展性和隨機存取解碼特性的位元流。書中附有許多圖表和表格以幫助理解。本書慷慨地指出了參考資料和資源,以幫助希望擴展知識、了解方法來源或尋找運行各種演算法或建立自己編碼系統資源的讀者。
