Abstract:
A one-dimensional, visual tracking chip has been implemented using neuromorphic,
analog VLSI techniques to model selective visual attention in the control
of saccadic and smooth pursuit eye movements. The chip incorporates focal-plane
processing to compute image saliency and to select a target feature for
tracking. The target position and direction of motion are reported as the
target moves across the array. The chip combines and extends previous neuromorphic
analog VLSI models of covert attentional processes and eye movement generation
to implement both saccadic and smooth pursuit tracking behavior using a
one-dimensional mechanical eye.
