Progressive Transmission of Continuous Tone Images Using Multi-Level Error Diffusion Method

摘要

We propose a new method of progressive trans- mission of continuous tone images using multi-level error diffusion method. Assuming that the pixels are ordered and the error is diffused to later pixels, multi-level error-diffused images are re- solved into a multiple number of bit planes. In an image with 8 bits per pixel, the number of the bit planes that we construct is 9, and the 2-level, 3-level, 5-level, …, error-diffused images are pro- duced by a successive use of the bit planes. The original image is finally achieved precisely.
