Abstract: A new method for data commmpression of multi-level still pictures is presented in this paper. The main advantage of the proposed procedures is based on the application of fixed-length code words. Consequently, this fact implies the considerably easier hardware and software implementation having in mind that there are no problems with the distinction of code words. Also, difficulties related to synchronization and resynchronization are less prominent using the suggested algorithm than in the case when variable code word methods are applied to data compression. The compression ratio obtained by the use of this method is evaluated for the well-known eight-level Lena picture. In this case with the defined gray level, the results of the achieved compression ratio are given.
Key words: Data compression, image processing.
