  Abstract
  A method for detecting precursors such as small rock and/or soil fall which occur prior to massive slope failure is proposed. Our method can be used to recognize a trajectory of a small collapse directly by using spatiotemporal Gabor filtering. Simulation analysis, where the conditions of the simulation are quantitatively defined, reveals the potential of the method detecting a tiny moving object with low contrast to the background under low frame-rate video monitoring. The practical factors in an outdoor environment, which may inhibit recognition, are also discussed.
