Optimal Lagrange Multipliers for Dependent Rate Allocation in Video Coding
In a typical video rate allocation problem, the objective is to optimally distribute a source rate budget among a set of (in)dependently coded data units to minimize the total distortion of all units. Conventional Lagrangian approaches convert the lone rate constraint to a linear rate penalty scaled by a multiplier in the objective, resulting in a simpler unconstrained formulation. However, the...
متن کاملOptimal rate allocation for video coding and transmission over wireless channels
An integrated framework of optimal rate allocation for video coding is presented in the case of transmission over wireless channels without feedback channels. For a fixed channel bit rate and finite number of channel coding rate, the proposed scheme can find the optimal source and channel coding pair and corresponding robust video coding scheme such that the expected end-to-end distortion of vi...
متن کاملOperational rate-distortion optimal bit allocation between shape and texture for MPEG-4 video coding
MPEG-4 is the first multimedia standard that supports the decoupling of a video object into object shape and object texture information, which consequently brings up the optimal encoding problem for object-based video. In this paper, we present an operational rate-distortion optimal hit allocation scheme between shape and texture for MPEG-4 encoding. Our approach is based on the Lagrange multip...
متن کاملOptimal rate allocation for macroblock-based progressive fine granularity scalable video coding
This paper addresses the problem of optimal rate allocation for the macroblock-based Progressive Fine Granularity Scalable (PFGS) video coding. To solve this complicated problem, the error propagation pattern in the macroblock-based PFGS is first investigated. An effective drifting model is established subsequently for estimating the drifting for each enhancement bit stream segment encoded by t...
متن کاملQuality-fluctuation-constrained rate allocation for MCTF-based video coding
This paper presents a new rate allocation algorithm for MCTF-based video coding with the aim to control quality fluctuation. Distortion analysis is conducted for MCTF using a simplified signal model. Based on the analysis, the aim to control quality fluctuation is posed as a quadratic programming problem and its solution forms the basis for our proposed algorithm. After discussions on some exte...
