Flow chart of the proposed computational model of bottom-up visual selective attention.

<p>It presents four aspects of the vision: perception, perceptual grouping, saliency map building and attention fields. The perception is to detect visual information and suppress the redundant by simulating the behavior of cortical cells. Perceptual grouping is used to build integrative feature maps. Saliency map building is used to fuse feature maps to obtain saliency map. Finally, attention fields are achieved from saliency map.
