Abstract

Compression of Images is one of the most actual and dynamic developing fields of Informatics and Informational Technologies.The suggested method for lossless compression of images requires that the image is presented as a set of 256 image levels, which must contain pixels from the initial image with identical intensity values.An algorithm containing 4 stages is applied to each level. Each stage of the algorithm is included depending on the satisfying of a criterion for closeness between the pixels of the level.The method can work as Iossless or as perceptually lossless depending on its settings.The method is universal and gives good results comparable to JPEG regarding images of different types and is open for further development at all stages.
