Abstract
The invention relates to a method for identifying and extracting images of one or more users in an interactive environment comprising the steps of: —obtaining a depth map () of a scene in the form of an array of depth values, and an image () of said scene in the form of a corresponding array of pixel values, said depth map () and said image () being registered; applying a coordinate transformation to said depth map () and said image () for obtaining a corresponding array () containing the 3D positions in a real-world coordinates system and pixel values points; —grouping said points according to their relative positions, by using a clustering process () so that each group contains points that are in the same region of space and correspond to a user location (); —defining individual volumes of interest () each corresponding to one of said user locations (); —selecting, from said array () containing the 3D positions and pixel values, the points located in said volumes of interest for obtaining segmentation masks () for each user; —applying said segmentation masks () to said image () for extracting images of said users. The invention also relates to a method for recognizing gestures of said users.
