Motion Capture
## Motion Capture ### Introduction Human motion capture has been a challenging research topic in computer vision and computer graphics for decades. The goal is to reconstruct a temporally coherent representation of the dynamically deforming surface of human characters from videos. A fast, low cost, easy to set up and promising for popularization systems is the long-term pursuit. ### Highlights ![](/projects/ai/MotionCapture/004.jpg) ####Free-viewpoint human performance capture with dynamic details - Multi-layer Avatar Digitization - Physics-Based Performance Capture > Yu, T., Zheng, Z., Zhong, Y., Zhao, J., Dai, Q., Pons-Moll, G., & Liu, Y. (2019). [SimulCap: Single-View Human Performance Capture with Cloth Simulation.](https://arxiv.org/abs/1903.06323). To appear in CVPR 2019 ![](/projects/ai/MotionCapture/003.jpg) ####Real-time motion capture by double fusion - Double-layer Representation - Joint Motion Tracking - Volumetric Fusion and Optimization > Yu, T., Zheng, Z., Guo, K., Zhao, J., Dai, Q., Li, H., ... & Liu, Y.
