  • receiving a depth image;

    generating a grid of voxels based on the depth image;

    determining whether one or more voxels in the grid are associated with a background by at least comparing a minimum depth value of the voxels in the grid with a reference plate comprising a depth history of the voxels in the grid;

    discarding the one or more voxels associated with the background to isolate voxels associated with a foreground object in the depth image; and

    processing the non-discarded voxels in the grid.
