SYSTEM AND METHODS FOR JOINT AND ADAPTIVE CONTROL OF RATE, QUALITY, AND COMPUTATIONAL COMPLEXITY FOR VIDEO CODING AND VIDEO DELIVERY |
摘要 |
System and methods for the joint control of reconstructed video quality, computational complexity and compression rate for intra-mode and inter-mode video encoding in HEVC. The invention provides effective methods for (i) generating a Pareto front for intra-coding by varying CTU parameters and the QP, (ii) generating a Pareto front for inter-coding by varying GOP configurations and the QP, (iii) real-time and offline Pareto model front estimation using regression methods, (iv) determining the optimal encoding configurations based on the Pareto model by root finding and local search, and (v) robust adaptation of the constraints and model updates at both the CTU and GOP levels. |
