    Reference frame list optimization algorithm in video coding by quality enhancement of the nearest picture by Junyan HUO, Ruipeng QIU, Yanzhuo MA, Fuzheng YANG

    Published 2022-11-01
    “…Interframe prediction is a key module in video coding, which uses the samples in the reference frames to predict those in the current picture, thus helps to represent the complex video by transmitting a small amount of the prediction residual.In lossy video coding, the qualities of reference frames are affected by the quantization distortion, which lead to poor prediction accuracy and performance degradation.Targeted at the low latency video services, a reference frame list optimization algorithm was proposed, which enhanced the quality of the nearest reference frame by a deep learning-based convolutional neural network, and integrated the enhanced reference frame into the reference frame list to improve the accuracy of interframe prediction.Compared with H.265/HEVC reference software HM16.22, the proposed algorithm provides BD-rate savings of 9.06%, 14.92% and 13.19% for Y, Cb and Cr components, respectively.…”

    UAV service enhancement mechanism deep deterministic policy gradient for scalable video coding transmission by Junjie YAN, Yaxin ZHU, Yanru FENG, Hanyong LIU, Junyi DENG, Huan WANG

    Published 2023-08-01
    “…Unmanned aerial vehicles (UAV) are an important component of future air-space-ground integrated network due to their onboard storage, communication, and computing capabilities.However, existing research on UAV-assisted edge networks often focuses more on the network perspective and lacks consideration of user perspectives and their requirements.Therefore, a UAV service enhancement mechanism based on deep deterministic policy gradient (DDPG) for scalable video coding (SVC) transmission was proposed from the user’s perspective.Firstly, an elastic video transmission method based on SVC was proposed in conjunction with UAV to improve differentiated user experiences.Secondly, a UAV trajectory planning design based on the DDPG algorithm was proposed to maximize the number of users receiving enhanced layer videos and ensure effective coverage enhancement by UAV in hotspot areas.Simulation results show that compared with both the deep Q network (DQN) algorithm and shortest path (SP) algorithm under different user distributions, the proposed algorithm can increase the average number of enhanced layers received by 47.9% and 76.4%, respectively.This study successfully achieves improved coverage in hotspot areas while also providing differentiated user experiences through its proposed methods.…”
