ABSTRACT:
A system and method for compressing an image into bit streams allows data to be presented in either lossy or lossless quality. A lossy quality presentation results in some measurable degradation of an image's visual quality upon expansion. A lossless quality presentation displays the image in its original form. The method divides the image to be compressed into a plurality of regions. For each region, a plurality of adjacent pixels are selected and organized into a set. The corresponding sets for each respective region are identified as a group. The pixel sets within each group are encoded and arranged into two bit streams associated with each respective group. Next, each group's respective bit streams are written into a primary bit stream of constant size and possible a supplemental bit stream of variable length for presenting the image in either lossy or lossless quality.
