Title Research and implementation of early action recognition algorithm based on human skeleton information

Abstract Early action recognition has a wide range of applications in computer vision， especially in human-computer interaction applications。The goal is to enable early recognition of unfinished actions as opposed to the after-the-fact classification of completed actions。In this paper,we implement a novel early action recognition algorithm which is based on human skeleton information。We use the Kinect sensor to accurately capture real-time three-dimensional data of the human skeleton,from which to calculate the normalized distance,generate templates and eventually to early recognize actions。In addition,a simple system which is able to early recognize actions has been developed in C# and WPF。This system can simultaneously display color images and human skeleton figure captured by Kinect sensor。At present,this system is capable of early recognizing eight specific actions。
