3D-BitNet: Flow-Agnostic and Precise Network for video Bit-Depth Expansion

Bit-depth expansion(BDE) algorithms have made great progress on single image. However, it is hard to directly apply on videos with no temporal constraint. Aiming at the problem of video BDE, we adopt an encoder-decoder structure with 3D convolution …

SpaAbr: Size Prediction Assisted Adaptive Bitrate Algorithm for Scalable Video Coding Contents

Dynamic Adaptive Streaming over HTTP(DASH) is a video transmission ptotocol to adapt to different network conditions and heterogeneous client devices. The client first requests and parses the Media Presentation Description(MPD) file from the DASH …

Video Enhancement Based on Unpaired Learning

Distortion of real video is affected by many factors. Many existing old videos n have the problem of low definition. However, most video enhancement based on paired learning is trained for specific degradation problem, lack of the ability to enhance …

A Generative Compression Framework For Low Bandwidth Video Conference

Video conferences introduce a new scenario for video transmission, which focuses on keeping the fidelity of faces even in the low bandwidth network environment. In this work, we propose VSBNet, one of the frameworks to utilize face landmarks in video …

Dual Attention Guided Gaze Target Detection in the Wild

Gaze target detection aims to infer where each person in a scene is looking. Existing works focus on 2D gaze and 2D saliency, but fail to exploit 3D contexts. In this work, we propose a three-stage method to simulate the human gaze inference behavior …

HEVC VMAF-oriented Perceptual Rate Distortion Optimization using CNN

Video coding standards like HEVC and VVC have achieved significant coding performance. However, the RDO module in coding framework ignores the characteristics of human visual system (HVS), which leads to insufficiency for perceptual video coding. …

SVM Based Fast CU Partitioning Algorithm for VVC Intra Coding

Recently, Joint Video Experts Team (JVET) has completed the new Versatile Video Coding (H.266/VVC) standard. VVC employs a new block partition structure named quad-tree with nested multi-type tree (QTMT) to improve coding efficiency. However, the new …

Deep Face Swapping via Cross-Identity Adversarial Training

Generative Adversarial Networks (GANs) have shown promising improvements in face synthesis and image manipulation. However, it remains difficult to swap the faces in videos with a specific target. The most well-known face swapping method, Deepfakes, …

DVRCNN: Dark Video Post-processing Method for VVC

Low-light videos are usually accompanied with acquisition noise, motion blur and some other specific distortions, which makes it hard to compress by the video coding technologies and generates less satisfying compressed videos. In order to enhance …
