1. A method of detecting feature points of an object in a system for motion detection, the method comprising: obtaining a first image of the object from a first camera and a second image of the object from a second camera; extracting a foreground image from each of the first image and the second image; based on an assumption that the foreground image is a T-pose image, segmenting the foreground image into a first set of sections; identifying a first set of feature points associated with the first set of sections; obtaining a T-pose image with a set of predetermined feature points; and determining whether the foreground image is a T-pose image by comparing the first set of feature points with the set of predetermined feature points.
