Shadow Gestures: 3D Hand Pose Estimation Using a Single Camera
نویسندگان
چکیده
This paper describes a system that uses a camera and a point light source to track a user's hand in three dimensions. Using depth cues obtained from projections of the hand and its shadow, the system computes the 3D position and orientation of two ngers (thumb and pointing nger). The system recognizes one dynamic and two static gestures. Recognition and pose estimation are user independent and robust. The system operates at the rate of 60 Hz and can be used as an intuitive input interface to applications that require multi-dimensional control. Examples include 3D ythru's, object manipulation and computer games.

Using a single RGB frame for real time 3D hand pose estimation in the wild
We present a method for the real-time estimation of the full 3D pose of one or more human hands using a single commodity RGB camera. Recent work in the area has displayed impressive progress using RGBD input. However, since the introduction of RGBD sensors, there has been little progress for the case of monocular color input. We capitalize on the latest advancements of deep learning, combining ...

متن کاملFast Tracking of Hand and Finger Articulations Using a Single Depth Camera
Using hand gestures as input in human–computer interaction is of everincreasing interest. Markerless tracking of hands and fingers is a promising enabler, but adoption has been hampered because of tracking problems, complex and dense capture setups, high computing requirements, equipment costs, and poor latency. In this paper, we present a method that addresses these issues. Our method tracks r...
