Neste artigo, propomos uma técnica de controle de taxa para H.264/AVC utilizando qualidade subjetiva de vídeo para codificação de vídeo off-line. Propomos usar Video Quality Metric (VQM) com um algoritmo de estratégia de evolução, que é capaz de identificar os melhores parâmetros de quantização possíveis para cada quadro/macrobloco para codificar a sequência de vídeo de forma que maximize a qualidade subjetiva de toda a sequência de vídeo submetida. à taxa de bits alvo. Os resultados da simulação sugerem que a técnica proposta pode melhorar significativamente o desempenho RD do codec H.264/AVC. Com a técnica proposta, pode ser alcançada uma redução de até 40% na taxa de bits com a mesma qualidade de vídeo. Além disso, os resultados mostram que a técnica proposta pode melhorar significativamente a qualidade subjetiva do vídeo codificado para sequências de vídeo, especialmente com alto movimento.

Abstract: In this paper, we propose a rate control technique for H.264/AVC using subjective quality of video for off line video coding. We propose to use Video Quality Metric (VQM) with an evolution strategy algorithm, which is capable of identifying the best possible quantization parameters for each frame/macroblock to encode the video sequence such that it would maximize the subjective quality of the entire video sequence subjected to the target bit rate. Simulation results suggest that the proposed technique can improve the RD performance of the H.264/AVC codec significantly. With the proposed technique, up to 40% bit rate reduction can be achieved at the same video quality. Furthermore, results show that the proposed technique can improve the subjective quality of the encoded video significantly for video sequences especially with high motion.
