The purpose of this study is to construct a mathematical model which predicts saliency regions in high-speed egocentric-motion movies by reproducing the properties of the area MST neurons' receptive fields. MST neurons detect global motions such as expansion, contraction, rotation, and so on. Our proposed model is based on a previous model which reproduces center-surround properties of the area MT neurons' receptive fields. MST neurons in the model integrate the responses of the MT neurons by convolving with spacial weight functions of which central portions are biased to preferred direction. The simulation results suggest that the modeled MST neurons can detect expansive motions from dynamic random-dot patterns and behave like the effective field of view. The results for the movies which were taken in a running vehicle indicate that the proposed model detects more salient objects around the vanishing point than the previous model. Furthermore, salient regions computed by our model are well similar to our experiential impression of the input movies. |
