Abstract :
We describe a model of invariant object recognition in the brain that incorporates feedback biasing effects of top-down attentional mechanism on a hierarchically organised set of visual cortical areas. The model displays a space based and a object based visual search by using a top-down attention feedback model from posterior parietal modules and interaction between the two processing streams dorsal and ventral.
