Pixel Cube: Diffusion-based Portrait Video Relighting Through Realistic Lighting Reproduction
Yufan Zhang, Yu Ji, Ayo Ajiboye +4
We present a diffusion-based method for relighting dynamic portrait videos with photorealism and temporal consistency. Our method is fueled by a hybrid training dataset that consis…
Seeing A 3D World in A Grain of Sand
Yufan Zhang, Yu Ji, Yu Guo +1
We present a snapshot imaging technique for recovering 3D surrounding views of miniature scenes. Due to their intricacy, miniature scenes with objects sized in millimeters are diff…
Light Field-Based Underwater 3D Reconstruction Via Angular Resampling
Yuqi Ding, Zhang Chen, Yu Ji +2
Recovering 3D geometry of underwater scenes is challenging because of non-linear refraction of light at the water-air interface caused by the camera housing. We present a light fie…
A Neural Rendering Framework for Free-Viewpoint Relighting
Zhang Chen, Anpei Chen, Guli Zhang +4
We present a novel Relightable Neural Renderer (RNR) for simultaneous view synthesis and relighting using multi-view image inputs. Existing neural rendering (NR) does not explicitl…
Non-Lambertian Surface Shape and Reflectance Reconstruction Using Concentric Multi-Spectral Light Field
Mingyuan Zhou, Yu Ji, Yuqi Ding +3
Recovering the shape and reflectance of non-Lambertian surfaces remains a challenging problem in computer vision since the view-dependent appearance invalidates traditional photo-c…
PIV-Based 3D Fluid Flow Reconstruction Using Light Field Camera
Zhong Li, Jinwei Ye, Yu Ji +2
Particle Imaging Velocimetry (PIV) estimates the flow of fluid by analyzing the motion of injected particles. The problem is challenging as the particles lie at different depths bu…
3D Face Reconstruction Using Color Photometric Stereo with Uncalibrated Near Point Lights
Zhang Chen, Yu Ji, Mingyuan Zhou +2
We present a new color photometric stereo (CPS) method that recovers high quality, detailed 3D face geometry in a single shot. Our system uses three uncalibrated near point lights…
Robust 3D Human Motion Reconstruction Via Dynamic Template Construction
Zhong Li, Yu Ji, Wei Yang +2
In multi-view human body capture systems, the recovered 3D geometry or even the acquired imagery data can be heavily corrupted due to occlusions, noise, limited field of- view, etc…
