It covers the JPEG compression algorithm that is mainly used for full color still image applications. The document describes all the components of the JPEG algorithm, including discrete cosine transformation, quantization and entropy coding. It also describes the architectures of the encoder and decoder. The main emphasis is given to the sequential operation mode which is the most typical use of JPEG compression; however, the other three operating modes are also described, progressive JPEG, lossless and hierarchical.
