Global 3D Non-Rigid Registration of Deformable Objects Using a Single RGB-D Camera
We present a novel global non-rigid registration method for dynamic 3D objects. Our method allows objects to undergo large non-rigid deformations, and achieves high quality results even with substantial pose change or camera motion between views. In addition, our method does not require a template prior and uses less raw data than tracking based methods since only a sparse set of scans is needed.
Robust Non-Rigid Registration with Reweighted Position and Transformation Sparsity
IEEE TVCG 2019 Won in the SHREC 2019 Contest
We propose a robust non-rigid registration method using reweighted sparsities on position and transformation to estimate the deformations between 3-D shapes.
Spatio-Temporal Reconstruction for 3D Motion Recovery
We address the challenge of 3D motion recovery by exploiting the spatio-temporal correlations of corrupted 3D skeleton sequences.
Tensor Completion From Structurally-Missing Entries by Low-TT-rankness and Fiber-wise Sparsity
JSTSP 2018
Most tensor completion methods assume that missing entries are randomly distributed in incomplete tensors, but this could be violated in practical applications where missing entries are not only randomly but also structurally distributed. To remedy this, we propose a novel tensor completion method equipped with double priors on the latent tensor, named tensor completion from structurally-missing entries by low tensor train (TT) rankness and fiber-wise sparsity.

ICME 2017 Code World’s FIRST 10K Best Paper Award – Platinum
We propose a new intrinsic image decomposition method that decomposing a single RGB-D image into reflectance and shading components.

We propose a marker-less performance capture method using sparse deformation to obtain the geometry and pose of the actor for each time instance in the database.

Graph-based Segmentation for RGB-D Data Using 3-D Geometry Enhanced Superpixels
IEEE Transactions on Cybernetics 2015
We propose a two-stage segmentation method for RGB-D data: 1) oversegmentation by 3-D geometry enhanced superpixels; and 2) graph-based merging with label cost from superpixels.

We propose a new method for temporal-densely capturing and reconstructing dynamic scenes with low frame rate cameras, which consists of spatio-temporal sampling, spatio-temporal interpolation, and spatio-temporal fusion.

Multi-Camera and Multi-Lighting Dome
We construct a dome to record the geometry, texture and motion of human actors in a dedicated multiple-camera studio with controlled lighting and a chromakey background. The diameter of the dome is 6 meters which provides enough space for character perform. 40 PointGrey flea2 cameras are ring-shape arranged on the dome and 320 LEDs are evenly spaced on the hemisphere of the dome.
