Abstract

Originally, JPEG standard was targeted for full-color still frame applications, achieving 15:1 average compression ratio [PM93, Wa191, Fur95]. However, JPEG has also been applied in some real-time, full-motion video applications (Motion JPEG - MJPEG). JPEG standard provides four modes of operation:
  • sequential DCT-based encoding in, which each image component is encoded in a single left-to-right, top-to-bottom scan

  • progressive DCT-based encoding, in which the image is encoded in multiple scans, in order to produce a quick, rough decoded image when the transmission time is long

  • lossless encoding, in which the image is encoded to guarantee the exact reproduction, and

  • hierarchical encoding, in which the image is encoded in multiple resolutions
