A method and apparatus to refine object boundaries of computer determined scene objects extracted from stereoscopic images is disclosed. In the method disclosed, a refinement of object boundaries is performed by altering the pixel combinations used to create scene objects. In this method, each pixel in a one image is re-combined with alternative pixels in a second image and a new disparity measure is determined for each of the re-matched pixel combinations. When the new disparity measure remains in dynamically specified boundaries the re-matched pixel combination is retained, thus, replacing a previous matched pixel combination. When the new disparity measure falls outside specified boundaries, a previous re-matched combination is retained. The process of altering pixel combinations by re-matching pixels between the stereoscopic images continues for each pixel of the combined image. |
