VASA-1: Lifelike Audio-Driven Talking Faces Generated in Real Time

no code implementations16 Apr 2024 Sicheng Xu, Guojun Chen, Yu-Xiao Guo, Jiaolong Yang, Chong Li, Zhenyu Zang, Yizhong Zhang, Xin Tong, Baining Guo

We introduce VASA, a framework for generating lifelike talking faces with appealing visual affective skills (VAS) given a single static image and a speech audio clip.

TypeFly: Flying Drones with Large Language Model

no code implementations8 Dec 2023 Guojun Chen, Xiaojing Yu, Lin Zhong

In this paper, we present a system called TypeFly that tackles the above three problems using a combination of edge-based vision intelligence, novel programming language design, and prompt engineering.

Relighting Neural Radiance Fields with Shadow and Highlight Hints

1 code implementation25 Aug 2023 Chong Zeng, Guojun Chen, Yue Dong, Pieter Peers, Hongzhi Wu, Xin Tong

This paper presents a novel neural implicit radiance representation for free viewpoint relighting from a small set of unstructured photographs of an object lit by a moving point light source different from the view position.


VirtualCube: An Immersive 3D Video Communication System

no code implementations13 Dec 2021 Yizhong Zhang, Jiaolong Yang, Zhen Liu, Ruicheng Wang, Guojun Chen, Xin Tong, Baining Guo

The VirtualCube system is a 3D video conference system that attempts to overcome some limitations of conventional technologies.

Depth Estimation

Object-based Illumination Estimation with Rendering-aware Neural Networks

no code implementations ECCV 2020 Xin Wei, Guojun Chen, Yue Dong, Stephen Lin, Xin Tong

With the estimated lighting, virtual objects can be rendered in AR scenarios with shading that is consistent to the real scene, leading to improved realism.

An online supervised learning algorithm based on triple spikes for spiking neural networks

no code implementations6 Jan 2019 Guojun Chen, Xianghong Lin, Guoen Wang

And then a computational method is constructed based on simple triple spikes using this direct regulation.

Robust Keyframe-based Dense SLAM with an RGB-D Camera

8 code implementations14 Nov 2017 Hao-Min Liu, Chen Li, Guojun Chen, Guofeng Zhang, Michael Kaess, Hujun Bao

In this paper, we present RKD-SLAM, a robust keyframe-based dense SLAM approach for an RGB-D camera that can robustly handle fast motion and dense loop closure, and run without time limitation in a moderate size scene.
