Progressive imaging on the Internet via WWW browser using adaptive block truncation coding

摘要

Abstract: A new progressive image transmission technique using adaptive block truncation coding is introduced in this paper. The adaptive block truncation coding was proposed as a non- transform coding mode for edge blocks in digital video sequences. By adapting more sophisticated just-noticeable-difference model of the human visual system, we can get an improved adaptive block truncation coding than the original work. With this improvement, we propose a progressive transport format of the adaptive block truncation coding so that we can reconstruct images in 3-pass coarse-to-fine manner. Simulation results on the adaptive block truncation coding is compared to those of JPEG and GIF. Through the transmission test via a World Wide Web browser, we can confirm the proposed transport format reduces bandwidth usage.!12
