Optimal Bit Allocation for Wavelet-Based Distributed Video Coding

Distributed video coding (DVC), based on the theorems proposed by Slepian-Wolf and Wyner-Ziv, is attracting attention as a new paradigm for video compression. Some of the DVC systems use intra-frame compression based on DCT. Correspondingly, we proposed a wavelet-based DVC system that utilizes the current JPEG 2000 standard. The scheme has scalability with regard to resolution and quality. However, related works does not offer that optimal bit allocation method for each sub-band coefficients. In this report, we propose a bit allocation method for a wavelet-based DVC scheme. Tests confirm that the PSNR is increased about 1-2[dB] by propose method
