Abstract

Peanoscanning was used to obtain the pixels from an image by following a scan path described by a space-filling curve, the Peano-Hilbert curve. The Peanoscanned data were then compressed without loss of information by direct Huffman, arithmetic, and LZW coding, as well as predictive and transform coding. The results were then compared with the results obtained by compressing equivalent raster scanned data to study the effect of Peanoscanning on image compression. In our implementation, tested on seven natural images, Peano- Differential coding with an entropy coder gave the best results of reversible compression from 8 bits/pixel to about 5 bits/pixel. An efficient implementation of the Peanoscanning operation based on the symmetry exhibited by the Peano-Hilbert curve is also suggested.
