JPEG File Format

• The JPEG compression algorithm a lossy method of compression that is most suitable for compressing TrueColor photographs and other continuous tone images.
  
  
• For images with sharp changes in tone, the format is less suitable and can introduce artifacts into the images.
  
  
• In JPEG compression, it is possible to control the amount of data lost by the compression process. In many software applications, you will find an option to control the Quality of the Save process:
  
  
  • Generally, a higher quality will result in less data loss, and fewer artifacts introduced into the image, but at the cost of higher file size.
    
    
  • Generally, a lower quality will result in more data loss, a smaller file size, but more artifacts introduced into the image.

• Compressed Image File Formats: JPEG, PNG, GIF, XBM, BMP (ACM Press)

  By John Miano Addison-Wesley Professional Paperback (288 pages) Amazon.com: Compressed Image File Formats is an appealingly compact and useful guide to some of today's most popular file formats used for image data. For any programmer who needs to know how images are stored, this concise reference can serve as a really invaluable resource. Besides full coverage of the popular BMP, GIF, and PNG file formats, the book zeroes in on the JPEG standard, perhaps today's most popular (and most complicated) image format. In a series of short chapters, the book looks at JPEG in detail, from basic file organization (its format and marker fields), file compression techniques (like Huffman coding and DCT), and how to decode (read) and encode (write) JPEG images. By condensing hundreds of pages of specifications and documentation from the voluminous JPEG standard into this short volume, the author has created a worthwhile summary of key JPEG features and compression techniques useful to any graphics programmer. The book also includes C++ code for a simple JPEG encoder (on the accompanying CD-ROM). This example can get you started compressing images using the JPEG format. In addition, the book discusses techniques for creating and decoding progressive JPEGs (used for downloading images in stages, in progressively finer resolutions, over the Internet). Whether you are a programmer faced with decoding or encoding image data, or an interested Webmaster who wants to know the pros and cons of today's image file formats, Compressed Image File Formats provides a worthwhile and concise reference to what's inside image files. --Richard Dragan Topics covered: bitmap basics, color models, Windows BMP file format, XBM file format, JPEG basics and file format, JPEG File Interchange Format (JFIF), JPEG Huffman Coding, data unit encoding, Discrete Cosine Transform (DCT), matrix operations, JPEG decoding and encoding, progressive JPEG, GIF file format and compression, and PNG file format.

• JPEG2000: Image Compression Fundamentals, Standards and Practice (The International Series in Engineering and Computer Science)

  Springer Hardcover (800 pages) Product Description: JPEG2000: Image Compression Fundamentals, Standards and Practice is an essential reference for professional engineers and academic researchers in the fields of communication, image processing, signal processing, information theory, and multimedia. It has specific applications for those involved in the development of software and hardware solutions for multimedia, internet, and medical imaging applications, and for those pursuing research in image and video compression. The book is suitable as a primary text for a course in image compression; it would also be helpful in the context of a more general class covering multimedia compression at an in-depth level. Final year engineering undergraduate students pursuing projects in multimedia compression and/or communication would also find the book a useful tool. JPEG2000: Image Compression Fundamentals, Standards and Practice is written in four parts, to serve the interests of a wide readership. Representing about half the total text, Part I of the book provides a thorough and up-to-date background in the fundamentals of image compression, including topics not previously brought together in a single volume. Part 2 contains a complete description of the JPEG2000 standard. This description is written in such a way as to be completely self-contained from an implementation perspective, while it contains numerous references to the fundamental developments in Part 1. Together, Parts 1 and 2 serve the complementary roles of explanation and exposition in relation to both the JPEG2000 standard and modern image compression techniques. Part 3 of the book is devoted to the implementation and exploitation of the JPEG2000 standard, containing guidelines, suggestions, and analyses for both software and hardware oriented applications. Part 4 describes other key image compression standards, namely JPEG and JPEG-LS. The purpose of this material is to allow the reader to compare the capabilities and complexity associated with these standards with those of JPEG2000. This final part of the book also serves to provide a practical demonstration of some of the fundamental techniques introduced in Part 1 which are not demonstrated by the JPEG2000 standard. About the CD-ROM: Included with the book is a compact disc containing documentation, binaries, and all source code to the Kakadu software tools. This software provides a complete C++ implementation of JPEG2000 Part 1, demonstrating many of the principles described in the text itself. The software is frequently referenced from the text as an additional resource for understanding complex or subtle aspects of the standard. Conversely, the software makes frequent reference to the text and has been written to mesh with the terminology and notation employed therein.
