Paper Abstract

Gray scale DF-expression (GDF) has raised some research interests recently. GDF-expression exploits data correlation on every bitplane and represents image hierarchically. In this paper, a predictive GDF-expression (PGDF) for lossless image compression is proposed which applies a predictive step to increase the spatial correlation on MSB bit-planes. The predictive GDF is compared with predictive Huffman encoding. Extensive experiments show that PGDF can achieve much better compression results than GDF and slightly better results than predictive Huffman encoding for most of the testing images.
