Claim One:
1. A method for identifying and extracting images of one or more users in an interactive environment comprising the steps of: obtaining a depth map ( 7 ) of a scene in the form of an array of depth values, and an image ( 8 ) of said scene in the form of a corresponding array of pixel values, said depth map ( 7 ) and said image ( 8 ) being registered; applying a coordinate transformation to said depth map ( 7 ) and said image ( 8 ) for obtaining a corresponding array ( 15 ) 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 ( 18 ) so that each group contains points that are in the same region of space and correspond to a user location ( 19 ); defining individual volumes of interest ( 20 ) each corresponding to one of said user locations ( 19 ); selecting, from said array ( 15 ) containing the 3D positions and pixel values, the points located in said volumes of interest for obtaining segmentation masks ( 35 ) for each user; applying said segmentation masks ( 35 ) to said image ( 8 ) for extracting images of said users.
