Abstract

En 中文
Lempel-Ziv-Welch (LZW) technique for text compression has been successfully modified to lossless image compression such as GIF. Recently, a new class of text compression, namely, Burrows and Wheeler Transformation (BWT) has been developed which gives promising results for text compression. Here, we propose a sub-block interchange lossless compression method which belongs to this block sorting class. Our compression results have outperformed GIF in compression ratios and BWT in compression times when tested with 512x512 pixel 8-bit grey scale images. The comparison of compression ratios and times with GIF, BWT and other popular LZ based compression methods are discussed.
