Talk title: Interaction-Oriented 4D Dynamic Scene Understanding
Abstract: Tremendous progress has been made for static 3D scene understanding over the last decade. However, detecting or segmenting 3D objects from static scenes fails to satisfy the needs of more and more critical applications such as human-assistant robots and augmented reality where the perception of interactions from dynamic 4D sensory inputs (e.g., temporal streams of colored point clouds) is required. Such 4D perception should unify semantic understanding with extraction and tracking of actionable information (e.g., parts, affordance, pose), which poses challenges to today’s 3D computer vision systems. We tackle these challenges from 4D dataset construction, 4D learning backbone design, and actionable information perception. In this talk, I will introduce our recent efforts on a large-scale 4D category-level human-object interaction dataset named HOI4D, which is designed to accelerate the understanding of dynamic human-object interaction in real scenes from a first-person perspective. I will also talk about our novel architecture design to support more effective and efficient deep learning on 4D point cloud sequences.

Talk title: Semantic Instance Reconstruction for 3D Scene Understanding
Abstract: 3D scene understanding and reconstruction plays very important roles in many application scenarios, like robot perception and also AR/VR etc. Currently, most of existing works treated the 3D scene as a whole unit for reconstruction. In this talk, I will introduce our recent techniques that conducted reconstruction together with instance understanding, which is termed as “Semantic Instance Reconstruction”. The main content includes two published works: Total3DUnderstanding (CVPR 2020) and RfD-Net (CVPR 2021). They are all aiming to semantic instance reconstruction, but Total3D focuses on reconstruction from single images while RfD-Net takes point cloud as input. In the next, I will also introduce an advanced technique for high-fidelity single-view 3D instance reconstruction.

Talk title: Accurate and Annotation-Efficient Deep 3D Rotation Regression
Abstract: 3D rotation estimation is an important technique in computer vision, graphics and robotics. In the deep learning era, deep 3D rotation regression modules become more and more popular and have been widely deployed to improve understanding of objects, humans, cameras and interactions in 3D scenes, thanks to its plug-and-play nature and end-to-end behavior. Despite of being widely used, deep rotation regression is still facing several major challenges that significantly limits its performance and usage. First, compared to coordinate-based approaches, directly regressing rotations has been suffering from low accuracy, given that rotations lie in SO(3), which is a non-Euclidean manifold and therefore very challenging to be directly regressed. Furthermore, fully supervised 3D rotation learning can’t be easily scaled up, since accurate 3D rotation anotations are very expensive and time-consuming to obtain. In this talk, I would introduce our recent efforts to make deep 3D rotation regressions more accurate and more annotation-efficient, including one CVPR 2022 oral work that introduces the first semi-supervised rotation regression framework, FisherMatch , along with another CVPR 2022 work, Regularized Projective Manifold Gradient (RPMG), that significantly improves the accuracy of rotation regression on a wide range of 3D scene understanding tasks via proposing a novel gradient layer.
