A Novel Data Compression
  A novel data compression scheme is presented. The method is very suitable for black and white images, and it can generate a compression factor of eight; in general the bitmap is optimized for an arbitary number of colors and not only for unused information contained in a conventional bitmap with $2^j$ bits per pixel. This compression method can be incorporated with other compression methods; it is suitable for other image types and audio. The potential high compression factor is cost effective for both memory and bandwidth requirements.
