AdaptNet: Policy Adaptation for Physics-Based Character Control

1 code implementation30 Sep 2023 Pei Xu, Kaixiang Xie, Sheldon Andrews, Paul G. Kry, Michael Neff, Morgan McGuire, Ioannis Karamouzas, Victor Zordan

The technique is shown to be effective for adapting existing physics-based controllers to a wide range of new styles for locomotion, new task targets, changes in character morphology and extensive changes in environment.

Composite Motion Learning with Task Control

1 code implementation5 May 2023 Pei Xu, Xiumin Shang, Victor Zordan, Ioannis Karamouzas

In contrast to existing data-driven approaches using reinforcement learning that imitate full-body motions, we learn decoupled motions for specific body parts from multiple reference motions simultaneously and directly by leveraging the use of multiple discriminators in a GAN-like setup.

A Real-time Hand Gesture Recognition and Human-Computer Interaction System

no code implementations24 Apr 2017 Pei Xu

The whole system consists of three components: hand detection, gesture recognition and human-computer interaction (HCI) based on recognition; and realizes the robust control of mouse and keyboard events with a higher accuracy of gesture recognition.
