N. Ohta et al., MOVING OBJECT DETECTION FROM OPTICAL-FLOW WITHOUT EMPIRICAL THRESHOLDS, IEICE transactions on information and systems, E81D(2), 1998, pp. 243-245
We show that moving objects can be detected from optical flow without
using any knowledge about the magnitude of the noise in the flow or an
y thresholds to be adjusted empirically. The underlying principle is v
iewing a particular interpretation about the flow as a geometric model
and comparing the relative ''goodness'' of candidate models measured
by the geometric AIC.
