Claim One:
1. A method for generating a composite output image from an input video having a sequence of frames, the method comprising: receiving a sequence of stereo video frames depicting a foreground object; for selected frames in the sequence of stereo video frames, performing by a processing device, foreground/background segmentations to extract respective stereo foreground object images each comprising a representation of the foreground object with background pixels subtracted; storing the respective stereo foreground object images to a foreground object list, each of the stereo foreground object images having left and right images with a disparity between them; transforming the stereo foreground object images to adjust the respective disparities between the respective left and right images based on a change between a convergence depth for the respective selected frames and a convergence depth for a current frame, the transforming of the stereo foreground object images comprising: decreasing the disparity for a given stereo foreground object image, in response to the convergence depth for the current frame being further away than a convergence depth for a selected frame corresponding to the given stereo foreground object; or increasing the disparity for the given stereo foreground object image, in response to the convergence depth for the current frame being closer than the convergence depth for the selected frame corresponding to the given stereo foreground object; and overlaying the transformed stereo foreground object images onto the current frame to generate a composite output image.
