Geometric programming duals of channel capacity and rate distortion
Channel capacity convex optimization duality free energy geometric programming rate distortion
2015/8/11
We show that the Lagrange dual problems of the channel capacity problem with input cost and the rate distortion problem are simple geometric programs. Upper bounds on channel capacity and lower bounds...
Rate-Distortion Optimization with Inter-View Refreshment for Stereoscopic Video Coding over Error-Prone Networks
Stereoscopic video coding error resilience inter-view refreshment end-to-end distortion model ratedistortion optimization
2013/7/16
Stereoscopic video is a practical and important manner for 3-D video applications, and robust stereoscopic video transmission over error-prone networks has posed a technical challenge for stereoscopic...
Rate Distortion Cost Modeling of Skip Mode and Early Skip Mode Selection for H.264
skip mode fast mod decion rate-distortion cost quantization
2013/7/16
This paper proposed a linear rate-distortion (RD) cost model for skip mode in H.264. The proposed RD cost model is derived theoretically based on the quantization scheme of H.264, and the simulation r...
