Sin3DM: Learning a Diffusion Model from a Single 3D Textured Shape

1 code implementation24 May 2023 Rundi Wu, Ruoshi Liu, Carl Vondrick, Changxi Zheng

Specifically, we encode the input 3D textured shape into triplane feature maps that represent the signed distance and texture fields of the input.

Humans as Light Bulbs: 3D Human Reconstruction from Thermal Reflection

no code implementations CVPR 2023 Ruoshi Liu, Carl Vondrick

The relatively hot temperature of the human body causes people to turn into long-wave infrared light sources.

Landscape Learning for Neural Network Inversion

no code implementations ICCV 2023 Ruoshi Liu, Chengzhi Mao, Purva Tendulkar, Hao Wang, Carl Vondrick

Many machine learning methods operate by inverting a neural network at inference time, which has become a popular technique for solving inverse problems in computer vision, robotics, and graphics.
