Temporal Filtering of Disparity Measurements

The paper proposes a temporal filtering technique for the disparity measurements generated by area-based stereomatching algorithms. The technique improves temporal consistency of disparity measurements by reducing the matching errors due to the noise affecting the imaging system. Moreover, the technique is capable of increasing the number of correct matches by locating uncertain measurements with a criterium based on statistical assumptions that has proven to be more accurate and selective than those relying on texture operators only which are typically deployed with standard area-based stereo algorithms.
