Abstract
A data re-ordering technique is proposed to enhance the compression performance of lossless LZW image compression over continuous-tone images. The proposed scheme incurs few overheads and functions as a preprocessing stage prior to actual compression. The compression performance is increased by an average of 18% for continuous-tone test images compared with the popular GIF compressor
