 note = {時空間ガボールフィルタを用いて時空間上の移動軌跡を抽出し，土砂災害の前兆現象となる落石や砂の崩落等を映像から検知する手法を検討した．シミュレーション映像を使って検討手法の定量的評価を行い，フレーム間差分法との比較を踏まえて検討手法の有効性を確認し，基本的な性質を明らかにした．また，霧の発生や木の揺れの外乱要因の検討手法に対する影響を評価した．, A method for detecting landslide precursor, such as small rock and/or soil fells which occur prior to massive landslide is proposed. The feature of our method is to recognize a trajectory of small collapse directly by using spatiotemporal Gabor filtering. The validity of our method is confirmed by simulation analysis where conditions of the simulation are quantitatively defined. The practical factors under real scene monitoring, which may disturb the recognition, are also evaluated.},
