1. A method for refining object boundaries using a first stereoscopic image of a scene and a second stereoscopic image of the scene, wherein corresponding pixels between said stereoscopic images are each matched as a single pixel entity having a first disparity measure, said method comprising the steps of: a. selecting one of said matched pixel entities; b. matching a corresponding pixel in said first image to an adjacent pixel in said second image to generate a re-matched pixel entity; c. determining a second measure for said re-matched pixel entity; d. retaining said re-matched pixel entity when said determined second measure is not substantially different from said first measure. e. repeating steps b through d for each pixel entity.
