Dalam kertas ini, kami mencadangkan teknik kawalan kadar untuk H.264/AVC menggunakan kualiti subjektif video untuk pengekodan video luar talian. Kami mencadangkan untuk menggunakan Metrik Kualiti Video (VQM) dengan algoritma strategi evolusi, yang mampu mengenal pasti parameter pengkuantitian terbaik yang mungkin untuk setiap bingkai/blok makro untuk mengekod jujukan video supaya ia akan memaksimumkan kualiti subjektif keseluruhan jujukan video yang tertakluk. kepada kadar bit sasaran. Keputusan simulasi menunjukkan bahawa teknik yang dicadangkan boleh meningkatkan prestasi RD codec H.264/AVC dengan ketara. Dengan teknik yang dicadangkan, pengurangan kadar bit sehingga 40% boleh dicapai pada kualiti video yang sama. Tambahan pula, keputusan menunjukkan bahawa teknik yang dicadangkan boleh meningkatkan kualiti subjektif video yang dikodkan dengan ketara untuk jujukan video terutamanya dengan gerakan tinggi.

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.
