Speech title: Visual sensing and tracking for robotic applications

AbstractVisual sensing and tracking are needed in many engineering applications including robotics. In this talk, I will present our research in visual sensing for automated 3D sensing in general and for motion tracking for robotics in particular. Different approaches in our investigation in 3D vision will be reported. These include an active vision approach to 3D visual sensing. For robotic applications, visual sensing in 3D is often needed, but the calibration remains tedious and inflexible with traditional approach. To this end, we have investigated the relevant issues for different visual sensing systems. A flexible calibration method desires the vision system parameters to be recalibrated automatically or with less operator interference whenever the configuration of the system is changed, but practically this is often hard to achieve. Various attempts were made in our previous works to enhance the flexibility in the visual sensing calibration. I will present some them including the work on omni-directional visual sensing and tracking. Another case to present is that of gaze tracking where the issues in the modeling and calibration are addressed with our new calibration method developed.

Speech Title: Next Generation of Video Coding Technology: Standards, Patent war, Politics, and Financial Battle

Abstract: This keynote talk is about next generation of video coding standards including Versatile Video Coding (VVC) and Video Coding for Machines (VCM). The presenter’s team has been working on these two standards and produced more than 60 patents in the field, which were assigned to the Boston’s company OP Solutions. The talk will include technical innovations, which make, for example, the VVC standard about 50% more efficient in terms of compression ratio than the present HEVC standard for the same quality of video. There are a range of evolutionary technologies in VVC, including intra prediction, inter prediction, transformation, in loop filtering, palette coding, block partitioning, affine motion, and decoder side search, which will be presented in the talk. Besides technical innovations, we will also talk about the process of VVC and VCM standard development, and technical and political war besides the scene. Video coding standards and related patents provide a great generator of revenue. Only Netflix pays about $400 million royalty for using video coding standard for distributing its movies. In order to avoid paying such royalties Google developed VP9 open royalty-free video coding system mainly used on Google’s video platform YuTube. Several powerful companies, Google, Microsoft, Amazon, Cisco, and Netflix have developed open-source video compression technology AV1, which competes with VVC standard. In this talk we will discuss technical and political issues, video coding standards vs open systems.

We will also present the new video coding standard in making, Video Coding for Machines. VCM attempts to bridge the gap between feature coding for machine vision and video coding for human vision. In the talk we will discuss the basic VCM encoder and decoder architecture, and our patent applications how to implement VCM and apply in many applications such as surveillance and transportation systems.

In the last part of the talk, we will discuss how the blockchain technology can be applied in video streaming. There is a trend that blockchain technology will change entertainment and streaming industry and will soon completely overthrow the current video streaming. The blockchain technology will allow that the video is decentralized among many nodes, so it can be watched everywhere. We will describe how the decentralized video streaming works and the benefits of the decentralized video streaming.
