Abstract
An image stored in a memory of a computer as pixels, each pixel including a bit pattern to indicate a grey-scale level. The image is compressed by grouping the pixels of the image into a plurality of regularized groups of pixels. The partitioning of the image can be in groups of four by four adjacent pixels. Groups of pixels having identical bit patterns are identified. The groups of pixels are encoded according to a frequency of groups of pixels having identical bit patterns.
