Claim One:
1. A method for creating a virtual viewpoint of a plurality of images captured by a plurality of cameras, the images comprising a plurality of current frames and previous frames, the method comprising: creating background frames by combining a set of previous frames; creating a plurality of foreground masks by performing segmentation on the plurality of current frames, the segmentation comprising separating foreground objects from background objects using the created background frames; extracting the foreground objects by AND-ing the plurality of current frames with the created plurality of foreground masks; rendering the foreground objects by using a three dimensional depth-box constrained viewpoint interpolation algorithm on the plurality of current frames, a three dimensional depth-box being constructed for each foreground object by exploiting information from the created plurality of foreground masks and positioning information of the foreground objects; rendering a view-dependent background image by performing homographic transformations on the created background frames; and creating the virtual viewpoint by superimposing the rendered foreground objects on the rendered view-dependent background image.
