Understanding the Visual World through Code
by Professor Jiajun Wu
Date: Friday, Nov. 5
Time: 17:30
Location: Online Call via Zoom

Our guest speaker is Jiajun Wu from Stanford University and you are all cordially invited to the CVG Seminar on Nov 5th at 5:30 p.m. on Zoom (passcode is 769629).


Much of our visual world is highly regular: objects are often symmetric and have repetitive parts; indoor scenes such as corridors often consist of objects organized in a repetitive layout. How can we infer and represent such regular structures from raw visual data, and later exploit them for better scene recognition, synthesis, and editing? In this talk, I will present our recent work on developing neuro-symbolic methods for scene understanding. Here, symbolic programs and neural nets play complementary roles: symbolic programs are more data-efficient to train and generalize better to new scenarios, as they robustly capture high-level structure; deep nets effectively extract complex, low-level patterns from cluttered visual data. I will demonstrate the power of such hybrid models in three different domains: 2D image editing, 3D shape modeling, and human motion understanding.
