Point Cloud Compression, Enhancement and Applications: From 3D Perception to Large Models

Point clouds have the strong capability for modeling 3D objects and scenes, which can be widely used in diverse applications and thus generate the burdens of transmission and storage. Efficient compression algorithms have been explored extensively, and research efforts have also been invested to enhancement algorithms. Moreover, the quality of point clouds can influence 3D analysis tasks, e.g., classification, segmentation, detection, and multimodal understanding, etc. Recent 3D multimodal large models can bring better perception optimizations. This tutorial will provide the fundamental knowledge for point cloud compression, enhancement and applications, and place emphasis on the influences of point cloud quality to human and machine perceptions. We will also discuss the progress of international standards and open source projects for point cloud technologies. From this tutorial, audiences are expected to grasp the basic knowledge and recent progress of point cloud technologies, and promote the research developments in both academia and industrial communities.
