Abstract
Completely parallel object recognition is NPcomplete. Achieving
a recognizer with feasible complexity requires a compromise be
tween parallel and sequential processing where a system selectively
focuses on parts of a given image, one after another. Successive
fixations are generated to sample the image and these samples are
processed and abstracted to generate a temporal context in which
results are integrated over time. A computational model based on a
partially recurrent feedforward network is proposed and made cred
ible by testing on the realworld problem of recognition of hand
written digits with encouraging results.
