GaussianFlow: Splatting Gaussian Dynamics for 4D Content Creation
Quankai Gao, Qiangeng Xu, Zhe Cao +5
Creating 4D fields of Gaussian Splatting from images or videos is a challenging task due to its under-constrained nature. While the optimization can draw photometric reference from…
Geometry-Aware Instance Segmentation with Disparity Maps
Cho-Ying Wu, Xiaoyan Hu, Michael Happold +2
Most previous works of outdoor instance segmentation for images only use color information. We explore a novel direction of sensor fusion to exploit stereo cameras. Geometric infor…
Grid-GCN for Fast and Scalable Point Cloud Learning
Qiangeng Xu, Xudong Sun, Cho-Ying Wu +2
Due to the sparsity and irregularity of the point cloud data, methods that directly consume points have become popular. Among all point-based models, graph convolutional networks (…
DISN: Deep Implicit Surface Network for High-quality Single-view 3D Reconstruction
Qiangeng Xu, Weiyue Wang, Duygu Ceylan +2
Reconstructing 3D shapes from single-view images has been a long-standing research problem. In this paper, we present DISN, a Deep Implicit Surface Network which can generate a hig…
Stochastic Dynamics for Video Infilling
Qiangeng Xu, Hanwang Zhang, Weiyue Wang +2
In this paper, we introduce a stochastic dynamics video infilling (SDVI) framework to generate frames between long intervals in a video. Our task differs from video interpolation w…
Report: Dynamic Eye Movement Matching and Visualization Tool in Neuro Gesture
Qiangeng Xu, John Kender
In the research of the impact of gestures using by a lecturer, one challenging task is to infer the attention of a group of audiences. Two important measurements that can help infe…
Generative Cooperative Net for Image Generation and Data Augmentation
Qiangeng Xu, Zengchang Qin, Tao Wan
How to build a good model for image generation given an abstract concept is a fundamental problem in computer vision. In this paper, we explore a generative model for the task of g…
