Dr. Zhigang Deng is Moores Professor of Computer Science and the Director of Graduate Studies at the Computer Science Department of University of Houston. He earned Ph.D. in Computer Science at the Department of Computer Science at the University of Southern California in 2006. He also completed B.S. degree in Mathematics from Xiamen University (China), and M.S. in Computer Science from Peking University (China). Over the years, he had worked at or consulted for the Founder Group (China), AT&T Research, Tencent USA, and Qualcomm.

His current research interests are in the broad areas of computer graphics, computer animation, virtual humans, human computer conversation, and robotics. He is the recipient of many awards including Moores Professorship, CASA Best Paper Awards, ACM ICMI Ten Year Technical Impact Award, UH Teaching Excellence Award, ICRA Best Medical Robotics Paper Award Runner-up, and Google Faculty Research Award. His research has been funded by NSF, NIH, NASA, DOD, Texas NHARP, QNRP, and various industry sources (Google, Honda, Electronic Arts, Nokia, etc). Besides serving as the conference general co-chair for both CASA 2014 and SCA 2015, he has been an Associate Editor for IEEE Transactions on Visualization and Computer Graphics, Computer Graphics Forum, Computer Animation and Virtual Worlds Journal, etc. His research work has been incorporated into many de facto graphics/animation packages (including Maya, and Houdini) and used in many game studios (e.g., Electronic Arts). He is an ACM distinguished member and an IEEE Senior Member.

Research Opportunities

I am constantly looking for new graduate or undergraduate students to join my group! Self-Motivated students with solid math, vision, or graphics background are encouraged to apply. If you are already a current MS or PhD student in UH Computer Science program and would like to work with me, please make sure to take COSC6372 and/or COSC6356 courses.

selected current projects

Butterfly Modeling and Simulation

An efficient and practical model to simulate butterfly flights including wing-abdomen interaction in various conditions and environments, based on parametric maneuvering functions and force-based models

Real-time Video-based Facial Performance Capture and Manipulation

Automatic algorithms to real-time capture 3D high-quality facial mesh sequences as well as video-based facial expression manipulation and face swapping

Analysis and Modeling Human Behaviors in Multiparty Conversations

Quantifying, understanding, and modeling human behaviors and gestures when they are involved with multiparty conversations

Skeletal Rigging from Mesh/Point Sequences

Using the input of an animated mesh sequence, this approach can automatically extract its optimal skeleton structure, joint positions, linear blend skinning weights, and the corresponding bone transformations.

Crowd Simulation and Evacuation

New algorithms and systems to simulate crowds or group behavior in unexpected hazard situations, computational model of crowd emotion evolution, or simulated crowds by integrating physical strength consumption

Visual Traffic Simulation, Modeling, and Evaluation

Design of novel and efficient algorithms and systems to simulate large-scale realistic traffic in various road and urban settings, including mixed traffic, lane-changing, simulated traffic evaluation, and intersectional traffic simulation.

3D Face Modeling from In-the-wild Images or Video

Automatic methods to reconstruct 3D face models with fine-scale details from a single in-the-wild image or video, including automatically augment coarse-scale 3D faces with synthesized fine-scale geometric wrinkles.

Data-driven Guzheng Playing Animation

A fully automatic, deep learning based framework to synthesize realistic upper body animations based on novel Guzheng music input. We design a generative adversarial network based approach to capture the temporal relationship between Guzheng music and human motion.

Hexahedral Mesh Generation, Optimization, and Evaluation

A first and complete pipeline to optimize the global structure of a hex-mesh, by identifying and removing those valid removal base-complex sheets that contain misaligned singularities, and a volumetric partitioning strategy based on a generalized sweeping framework to seamlessly partition the volume of an input triangle mesh into a collection of deformed cuboids.

Interactive Complex Object Modeling from Multi-view Images

development of a novel interactive modeling approach based on multi-view images including interactive 3D modeling and stochastic motion parameter estimation.
