Gesture track recognition based on Kinect depthimage information and its applications
基于Kinect深度图像信息的手势轨迹识别及应用

In order to realize the gesture track recognition based on the depth image information got by the Kinect sensor, this paper presented a new method. First, it used Kinect sensor to obtain depth image information. Then it obtained the position of palm through OpenNI hand analysis module, and extracted trajectory feature. Finally, it adopted Hidden Markov modelHMMtrained effective track sample and achieved track recognition. Experiments results show that the presented method can effectively identify the gesture track, and apply to control intelligent wheelchair.
