FTP, indetify this standard for the compression of still images.
This standard is named after a group formed in a cooperative effors of the ISO, ITU, and IEC. The method starts with a discrete cosine transform, which results in several 8x8 matrices of spatial frequencies. During the quantization phase, the matrices are modified by another matrix, usually chosen to compress well with minimal loss. The final encoding phase linearizes the two-dimensional data and then compresses it. Although it does result in information loss, this is usually tolerable with image data.
