Abstract (in Japanese) (See Japanese page) 
(in English) The purpose of this study is to construct a mathematical model which predicts saliency regions in high-speed egocentric-motion movies. The proposed model was considered the spatial differentiation by the center-surround organization of receptive fields, time response characteristics which generate visual adaptation, and motion feature extraction by higher order motion detection mechanism in the middle tempral area (MT) and the medial superior temporal area (MST). We simulated by using high-speed egocentric-motion movies, filmed by an embedded camera in a driving vehicle, and compared it with human scan-path data. The simulation results indicate that the proposed model detects more salient objects around the vanishing point than the conventional saliency based model. The moving-NSS scores, the index of prediction-accuracy of focal attention area, are significantly higher in our model than those of the conventional saliency estimation models. These results suggest that the proposed model is able to predict the focal attention area similar to the human visual perception in the high-speed self-motion image.
