Previous saliency-based visual attention models dealt with the mechanism underlying attentional shifts in the early visual system. Such models can predict the distribution of gaze movements on the basis of saliency maps (Itti \& Koch, 2000). Saliency maps are calculated by weighting to the distribution of color and the orientation of input images. Since predicted gaze positions using the previous saliency map models are deterministically selected by tracing the peaks of saliency distribution, the simulated trajectories of gaze positions show non-contextual and unnatural patterns. In this study, we purposed a mathematical model to reproduce more realistic gaze distributions. We have carried out an extension of the saliency map taking into account the spatio-temporal characteristics of attention for the visual attributes, and also image projection from retina to V1; cortical magnification factor. To evaluate the performance of our model, we conducted visual search task simulations. The results indicate that the target detection rate of our model are higher than that of Itti \& Koch's model and simulated gaze distributions show contextual patterns while searching for the target. |
