An isolated sign language recognition system is presented in this paper. A RGB-D sensor, Microsoft Kinect, is used for obtaining color stream and skeleton points from the depth stream. For a particular sign we extract a representative feature vector composed by hand trajectories and hand shapes. A sparse dictionary learning algorithm, Label Consistent K-SVD(More)
In this paper, a vision-based adaptive control is designed for a wheeled inverted pendulum (WIP) robot to track a moving human target by integration of multisensor data. A new algorithm is employed in the system to combine an OptiTrack camera and a Kinect camera, such that more robust and efficient performance can be achieved for human target detection and(More)
This paper presents the nonholonomic navigation and obstacle-avoidance control method for a developed wheeled chair. The nonholonomic navigation technology is based on SLAM, in addition, a new method of collision avoidance control is proposed for this latter. The method makes the wheeled chair move intelligently and avoid obstacle with more efficient and(More)
