About me

I am a researcher and group leader at the Rakuten Institute of Technology. My current interests are in machine learning applied to computer vision, video processing and generative design.

Prior to Rakuten I was at Toshiba Research (archived page). I completed my PhD in computer vision at the University of Cambridge in Roberto Cipolla's group, co-supervised by Philip Torr. My Diplom in Computer Science is from the University of Bonn. During my studies, I spent time at the University of Victoria, Hewlett-Packard, and Siemens Corporate Research.

BigHand2.2M Benchmark: Hand Pose Data Set and State of the Art Analysis
S. Yuan, Q. Ye, B. Stenger, S. Jain, T.-K. Kim,
CVPR, July 2017.

We captured a new standard dataset for 3D hand pose estimation. Depth maps are accurately annotated with 3D joint locations using a magnetic tracking system. We show that training a CNN on this data achieves accurate results. The data was used in the Hands in the Million Challenge.
