Abstract :
A new method for overcoming bas-relief ambiguity, using a calibrated stereo image sequence, is presented. The proposed method uses a direct method for motion estimation as the initial guess, and refines both stereo and motion displacement with sub-pixel accuracy. Experimental results show that the proposed algorithm improves the estimation accuracy under such ambiguity
