Saliency map models are mathematical expressions of the characteristics of bottom-up attention processing (Itti & Koch, 2000). The saliency maps are calculated by weighting to the distribution of color and the orientation of input images on the bases of the physiological knowledge of early visual system. In late years, saliency-based models were modified to predict gaze positions for moving objects. However, these models have not been taken into the neural response characteristics of motion detection area in the brain, such as the area MT. The purpose of this study is to calculate the saliency maps for the motion components in moving images by reproducing the properties of the area MT neurons' receptive fields involved in motion perception. To evaluate the performance of proposed model, we conducted simulation experiments for the motion pop-out stimulus. The simulation results suggest that the proposed model can pick up the pop-out region more sensitively than the previous model. Furthermore, the simulation results for the movies of natural scenery, our model persistently responds to the region in which certain motion contrasts are contained whereas the previous model responds intermittently. |
