1. A method for processing data, comprising:

  • receiving a temporal sequence of depth maps of a scene containing a stationary background and one or more moving foreground objects that conceal a part of the background, the depth maps comprising a matrix of pixels, at least some of which have respective pixel depth values and correspond to respective locations in the scene;

    using a digital processor, processing a first depth map in the sequence so as to identify a first portion of the stationary background that is not concealed by the moving foreground objects in the first map;

    processing at least a second depth map in the sequence so as to identify at least a second portion of the stationary background, which is different from the first portion due to motion of at least one of the foreground objects over the sequence; and

    constructing a background model of the scene by combining at least the first and second portions of the stationary background.
