Abstract :
The paper presents a lossless compression method, based on the variation of the byte length of data elements in the sequence. The method has been developed and analyzed in the field of image compression. The purpose of creating such an algorithm was to simplify the hardware realization of the image compression and save hardware area and memory resources. It is used after DCT transformation along with different quantization method comparing to JPEG encoding. Results of the algorithm are compared to JPEG compression results.
