Abstract :
We analyze the performance of context-based lossless image coding techniques in conjunction with the Hilbert and raster scans. Our analysis shows that, under certain reasonable assumptions, the raster scan is indeed better than the Hilbert scan, thereby dispelling the popular notion that using a Hilbert scan would always lead to improved performance.
