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