This paper presents a novel rate control algorithm for H.264/AVC video coding. Pertinent to the algorithm, the paper introduces a joint R-D model, a coding bit estimation approach, a picture complexity measurement, and a model update method. Specifically, the proposed picture complexity measurement employs a harmonic mean based approach to predict the coding complexity of a frame. These techniques...
In this paper, we present a robost frame level rate control algorithm for H.264/AVC compression standard. Particularly, we propose a simple yet effective approach to deal with B frames, including a PSNR-QP model and an adaptive QP computation method for B frames. The objective is to reduce PSNR variations among frames and improve subjective visual quality. To better handle buffer fullness and reduce...
In this paper, we propose a new incremental rate control scheme for H.264/AVC video coding, which elegantly resolves the "Chicken and Egg" dilemma by eliminating the need of coding complexity prediction for inter-frames. The proposed scheme introduces a number of new features, including a rate- complexity-quantization model, accurate quantization parameter (QP) estimation for intra-frames,...
