Psychophysical Measurement of Attentional Modulation in Low-Level Vision Using the Lateral-Interactical regions of a scene, a perception of the overall structure and also of the distinctiveness of the separate objects contained within it. A long standing debate in psychology concerns the extent to which perceptual processes are autonomous, operating independently of top-down attentional control.–.

Log-Map Analysister a feature extraction phase, the image content is analysed and interpreted or classified. This open loop paradigm does not support real-time processing, even for the simplest tasks that humans perform without effort.

Bottom-Up and Top-Down Mechanismsced with a fundamentale dilemma: is visual perception the result of bottom-up or of top-down mechanisms? Extremizing a little, we can say that the kind of answer given to this question subdivides the theories of perception into two different categories, corresponding to two entirely different, and c

These two processes have been termed respectively pre-attentive and attentive visual segmentation of targets against backgrounds. This paper analyzes computational strategies for se

CHARM

Stimulus-Driven and Goal-Directed Attentional Controlcted for further processing and irrelevant ones are ignored. The control of attention is usually assumed to be of two types: top-down or goal-directed control on the one hand, and bottom-up or stimulus-driven control on the other. In most cases, some combination of these two influences determines ho
