Low density codes achieve the rate-distortion bound
Abstract: We propose a new construction for low-density source codes with multiple parameters that can be tuned to optimize the performance of the code. In addition, we introduce a...

Mismatch Impact on Per-Pixel End-to-End Distortion Estimation and Coding Mode Selection
The recursive optimal per-pixel estimate (ROPE) is an effective end-to-end distortion estimation scheme. Most existing ROPE-based applications assume that: (i) the encoder knows e...
