Abstract :
In this paper, we propose a simple search order entropy coding algorithm to compress grey level scale images on lossless basis. Extensive experiments are carried out in comparison with JPEG lossless compression mode. The results reveal that for the majority of image samples tested, the proposed algorithm outperforms JPEG. This work provides a competitive alternative yet simple solution to lossless image compression.
