1. A method for automatically segmenting a sequence of two-dimensional digital images into a navigable 3D model, said method including:

  • a) capturing image sequences and defining nearer matte layers and/or depth maps based on proportionately greater lateral motion;

    b) generating a wireframe surface for background and foreground objects from the raw video data which has been captured and processed in step (a);

    c) giving depth to foreground objects using either;

    silhouettes from different perspectives, center spines that protrude depthwise in proportion to the width up and down the object, or motion parallax information if available;

    d) texture mapping the raw video onto the wireframe;

    e) filling in occluded areas behind foreground objects, both on the background and on sides that are out of view, by stretching image edges in to the center of blank spots; and

    f) sharpening surface images on nearer objects and blurring more distant images to create more depth perception, using either existing video software development kits or by writing image processing code that implements widely-known convolution masks, thereby automatically segmenting an image sequence into a 3D model.
