Quality of experience (QoE) is the perceptual quality of service (QoS) from the users'
perspective. For video service, the relationship between QoE and QoS (such as coding …

Delivering real-time video over the Internet is an important component of many Internet
multimedia applications. Transmission of real-time video has bandwidth, delay, and loss …

This article proposes an end-to-end learnt lossy image compression approach, which is built
on top of the deep nerual network (DNN)-based variational auto-encoder (VAE) structure …

Video coding, which targets to compress and reconstruct the whole frame, and feature
compression, which only preserves and transmits the most critical information, stand at two …

The compression capability of several generations of video coding standards is compared
by means of peak signal-to-noise ratio (PSNR) and subjective testing results. A unified …

Rate control is a useful tool for video coding, especially in real-time communication
applications. Most of existing rate control algorithms are based on the RQ model, which …

This paper presents an overview of the technologies for in-loop processing and filtering in
the Versatile Video Coding (VVC) standard. These processes comprise luma mapping with …

This paper provides a technical overview of a newly added in-loop filtering technique,
sample adaptive offset (SAO), in High Efficiency Video Coding (HEVC). The key idea of SAO …

This paper proposes a deep learning method for intra prediction. Different from traditional
methods utilizing some fixed rules, we propose using a fully connected network to learn an …

In region-of-interest (ROI)-based video coding, ROI parts of the frame are encoded with
higher quality than non-ROI parts. At low bit rates, such encoding may produce attention …
