Abstract :
This paper proposes a statistical rejection rule, designed for small baseline stereo satellites. The method learns an a contrario model for image blocks and discards the casual matches between the images of the stereo pair. A formula estimating the expected number of false alarms under the background model is proved. Comparative experiments on quasi-simultaneous stereo in aerial imagery demonstrate the elimination of all incoherent motions.
