Transform coding of images
Abstract
The theoretical and practical aspects of transform coding systems for processing still or moving images are discussed. Among the specific topics considered are: the statistical properties of images; orthogonal transforms for image coding; and transform coefficient quantization and bit allocation. Some practical methods of image coding are described, including: interframe coding; intraframe coding; and transform coding of color data. The application of human visual models to the assessment of image quality is also discussed. Techniques for measuring rms error in coded images are given in an appendix.
