Paper Abstract

In this paper, we propose a robust quantizer design for image coding. Because the bits representing the reconstruction levels are transmitted directly to the channel, the proposed quantizer can be viewed as a compound of a quantizer, a VLC coder, and a channel coder. The conventional combined source/channel design produces a source coder designed for a channel with a specific channel noise. Our proposed quantizer is designed within a noise range. In comparison with the ordinary JPEG coder, simulation results show that our proposed scheme has a much more graceful distortion behavior within the designed noise range.
