Point Cloud Compression and Communication
Zhu Li, PH.D.
University of Missouri, Kansas City
Point cloud data arises from 3D sensing and capturing for both auto driving/navigation/smart city, as well as VR/AR playback and immersive visual communication applications. Recent advances in sensor technology and algorithms, especially LiDAR and 77Ghz mmWave radar systems, and very high resolution RGB camera arrays, have made point cloud capture getting closer to wide adoption in real world applications. In this talk I will overview the related research at the Multimedia Computing & Communication Lab at UMKC, discuss the main technical challenges and solutions in point cloud capture, compression and communication, especially the scalable geometry compression, MPEG video based point cloud compression (PCC) problems, and our recent results in advanced 3D motion model, occupancy map driven rate-distortion optimization and learning based point cloud QoE metrics that significantly advanced the state of art in video based PCC.
