Since not all graphic formats are of equal complexity, author John Miano does not simply choose a number of file formats and devote a chapter to each one. Instead, he offers additional coverage for the more complex image file formats like PNG (a new standard) and JPEG, while providing all information necessary to use the simpler file formats. While including the well-documented BMP, XBM, and GIF formats for completeness, along with some of their less-covered features, this book gives the most space to the more intricate PNG and JPEG, from basic concepts to creating and reading actual files. Among its highlights, this book covers: -- JPEG Huffman coding, including decoding sequential mode JPEG images and creating sequential JPEG files-- Optimizing the DCT-- Portable Network Graphics format (PNG), including decompressing PNG image data and creating PNG files-- Windows BMP, XBM, and GIF
A substantially updated edition of Video Coding: An Introduction to Standard Codecs, (IEE, 1999) this book discusses the growth of digital television technology and the revolution in image and video compression (such as JPEG2000, broadcast TV, and video phone), highlighting the need for standardization in processing static and moving images and their exchange between computer systems. ITU and ISO/IEC standards are now widely accepted in the picture/video coding field. The book gives an authoritative explanation of picture and video coding algorithms, working from basic principles through to the advanced video compression systems now being developed. One of its main objectives is to describe the reasons behind the introduction of a standard codec for a specific application and its chosen parameter. This book will enable readers to appreciate the fundamentals needed to design a video codec for any given application and should prove to be a valuable resource for engineers working in this field.
