Noise Thresholds for Discrete LDPC Decoding Mappings
— For decoding low-density parity-check (LDPC) codes on discrete memoryless channels, a method to quantize messages and to find message-passing decoding functions for the variab...

Denoising intra-coded moving pictures using motion estimation and pixel shift
This paper presents a denoising method of intra-coded pictures using motion estimation and pixel shift. Firstly, we show that pixel-aligned mixture of distorted images which are s...

Frame based multiple description image coding in the wavelet domain
Multiple description codes generated by quantized frame expansions have been shown to perform well on erasure channels when compared to traditional channel codes. In this paper we...
