Quantizer Design in Wyner-Ziv Distributed Video Coding Systems

This report outlines advanced quantizer design strategies for Wyner-Ziv distributed video coding presented by Professor Yang Shih-Hsuan and reported by student Li Tong-Zhao. It includes an introduction to distributed video coding principles, the design of quantizers, and simulation results demonstrating the performance of various quantization methods. The study further explores the use of side information to enhance source value distinction and concludes with insights on the efficiency of Wyner-Ziv systems in relation to SPIHT coding rates, along with suggested future work in quantizer implementation.
