|
Vision-based 3D Human Reconstruction Co-Investigator |
Python |
|
A collaborative research project with Tan Tock Seng Hospital (TTSH), Singapore. Developed a multi-camera system and 3D reconstruction pipeline using SMPLer-X for full-body modeling and HaMeR for hand reconstruction. Built a kinematic analysis system to evaluate stroke patients' motor function and rehabilitation progress through both clinical tasks and daily life activities. |
