System and method for selecting features for identifying human activities in a human-computer interacting environment
Abstract:
A System and method for identifying one or more human activities in a human-computer interacting environment. Skeleton points associated with a human are received. A data variation factor for the skeleton points is calculated, and a set of skeleton points is selected based on the data variation factor. One or more features are defined from the set of skeleton points by identifying a variance in coordinates of the set of skeleton points by using one or more statistical parameters. The one or more features are used to identify the one or more human activities.
Abstract(Chinese):

一种用于识别人机交互环境中的一个或多个人类活动的系统和方法。 收到与人相关联的骨骼点。 计算骨架点的数据变化因子，并根据数据变异因子选择一组骨架点。 通过使用一个或多个统计参数来识别该组骨架点的坐标方差，从该组骨骼点定义一个或多个特征。 一个或多个特征用于识别一个或多个人类活动。
