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. …

An Elastic System Architecture for Edge Based Low Latency Interactive Video Applications

5G and edge computing have brought great changes to video industry. Interactive video is becoming an emerging application form of multimedia service, which provides attraction beyond typical scenarios like cloud gaming and remote virtual reality …

VMAF Oriented Perceptual Coding Based on Piecewise Metric Coupling

It has been recognized that videos have to be encoded in a rate-distortion optimized manner for high coding performance. Therefore, operational coding methods have been developed for conventional distortion metrics such as Sum of Squared Error (SSE). …

A VMAF Directed Perceptual Rate Distortion Optimization for Video Coding

Video Multimethod Assessment Fusion (VMAF), as a state-of-the-art learning-based objective assessment metric, has been demonstrated to achieve a stronger correlation with human visual system than others. However, combining multiple metrics by Support …

A Generic Method to Improve No-Reference Image Blur Metric Accuracy in Video Contents

We present in this work a generic and effective method to increase the prediction accuracy of no-reference image/video blur assessment facing the real-world content diversity. We demonstrate that benchmarking no reference image blur metrics, fitting …

Fast single depth intra mode decision for depth map coding in 3D-HEVC

In 3D-HEVC, single depth intra mode has been applied and has been integrated into depth intra skip mode for efficient depth map coding. With single depth intra mode, one 2N×2N prediction unit (PU) is predicted without high computational prediction …

Shaking video synthesis for video stabilization performance assessment

The goal of video stabilization is to remove the unwanted camera motion and obtain stable versions. Theoretically, a good stabilization algorithm should remove the unwanted motion without the loss of image qualities. However, due to the lack of …
