....location is from its surrounding. A Winner Take All (WTA) neural network implements the selection process based on the saliency map to govern the shifts of visual attention. This model performs well on many natural scenes and has received some support from recent electrophysiological evidence [35,76]. Tsotsos et al. 88] presented a selective tuning model of visual attention that used inhibition of irrelevant connections in a visual pyramid to realize spatial selection and a top down WTA operation to perform attentional selection. In the model proposed by Clark et al. 9,10] each ....

....the modulation of driven activity with eye position is still a true gain effect and not a simple additive effect. Hence, the fixation and gain effects could arise from independent sources. Likely sources for the eye position sensitivity in area 7a include the pulvinar (Robinson et al. 1990; Robinson and Petersen, 1992) and cortico cortical inputs from LIP (Andersen et al. 1990) or even feedback from the frontal eye fields (Cavada and Goldman Rakic, 1989) An interesting and novel finding in the present study is the convergence and interaction between mechanisms for extraction of optic f low pattern and angle ....

....[TG80] NK96] Peak values in this saliency map correspond to areas of high visual interest and visual attention is preferably directed to these locations. Indeed, there are several hints for the existence and location of a saliency map in biological visual systems [PRM87] KMKI88] LB90] DWTS91] [RP92]. In our approach, we concentrate on low level visual attention and design a hierarchical model consisting of three modules. Each module processes visual information at a finer and smaller region of interest (RoI) than its preceding module (see Fig. 4) Therefore, the number of operations ....

.... spatial layout as part of its role in visual orienting behaviors (Hughes, 1982; Lesperance, 1990; Trevarthen, 1968) there is also evidence that the pulvinar may be involved in assessing salience of visual stimuli and in attentional processes (Marrocco and Li, 1977; Robinson and McClurkin, 1989; Robinson and Petersen, 1992; Van Essen, Anderson and Felleman, 1992) However, the bulk of the processing that leads to visual perception in higher primates and humans is believed to take place in the cortex itself, and in the present research I will focus entirely on the cortex. The portion of the cortex receiving the bulk ....

The model s saliency map is endowed with internal dynamics which generate attentional shifts. This model consequently represents a complete account for bottom up saliency, and does not require any top down guidance to shift attention. This framework provides a massively parallel method for the ....
