Abstract: 
We discuss the lossless image compression algorithms which are used in the modern data base communication systems for upgrading the efficiency of the channels with insufficient transmitting capacity. A new approach is proposed for lossless compression in which the image decorrelation is based on the analysis of brightness differences, coding of most significant digits in neighboring pixels, and interpolation, without recourse to the hierarchical image decomposition. These algorithms were compared with well-known hierarchical algorithms for lossless compression.
Keywords: data base communication systems, image decorrelation, lossless image compression
