基于Leap Motion传感器的自适应动态手势识别
ADAPTIVE DYNAMIC GESTURE RECOGNITION BASED ON LEAP MOTION
摘要
Abstract
Gesture recognition based on vision is a key technology to realize new human-computer interaction.To the problem of gestures adaptability and recognition rate,a new method of adaptive dynamic gesture recognition based on the Leap Motion is presented on the basis of improving Hidden Markov Model (HMM).Firstly,by using the method of geometric features to recognize the static hand posture,the start and end point of dynamic gesture trajectory could be confirmed.After extracting and classifying gesture trace features by angle,the revised revaluation method is introduced to calculate model parameters.Finally,with recognizing the undefined gesture,the method of automatic learning and updating HMM is presented to improve the efficiency of the gesture recognition,and the dynamic gesture recognition of 26 lowercase letters is realized in the end.Experimental results show this method has a good adaptability and accuracy performance in dynamic gesture recognition.关键词
