Abstract: Point cloud data arise from depth sensing and capturing for both auto driving/navigation/smart city, as well as immersive content capture and VR/AR playback applications. Recent advances in sensor technology and algorithms, especially 77Ghz MIMO radar systems, and high resolution structured light in conjunction with very high resolution RGB camera arrays, have made point cloud capture getting closer to 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 for auto driving and smart city applications,  especially the scalable geometry compression, as well as the video based attributes compression problems, we will introduce our recent results in advanced 3D motion model, occupancy map driven rate-distortion optimization and multi-attribute compression that significantly advanced the state of art in video based PCC.
