DESCRIPTION:*Abstract*\n\nUnderstanding the 3D structure of real-world env
 ironments is a fundamental challenge in machine perception\, with many app
 lications towards robotic navigation and interaction\, content creation\, 
 and mixed reality scenarios. In this talk\, we propose to develop an objec
 t-centric perspective on 3D perception. We first explore 3D CAD-based prio
 rs to represent objects to attain a compact representation space from whic
 h we can develop robust retrieval and alignment to image observations. We 
 then relax the constraint on retrieval from a database to learn parametric
  models to represent shapes and parts\, followed by developing a parametri
 c model for the manifold of 3D scenes. Finally\, we show that an object ba
 sis not only helps to perform semantic reconstruction\, but can also signi
 ficantly benefit camera tracking for RGB-D video observations -- providing
  the potential for holistic reconstruction and understanding from an objec
 t-guided perspective.\n\n*Bio*\n\nAngela Dai is an Assistant Professor at 
 the Technical University of Munich where she leads the 3D AI group. Prof. 
 Dai's research focuses on understanding how the 3D world around us can be 
 modeled and semantically understood. Previously\, she received her PhD in 
 computer science from Stanford in 2018 and her BSE in computer science fro
 m Princeton in 2013. Her research has been recognized through a Eurographi
 cs Young Researcher Award\, Google Research Scholar Award\, ZDB Junior Res
 earch Group Award\, an ACM SIGGRAPH Outstanding Doctoral Dissertation Hono
 rable Mention\, as well as a Stanford Graduate Fellowship.\n\n*Location*\n
