Color indexing
Michael J. Swain,Dana H. Ballard +1 more
TL;DR: In this paper, color histograms of multicolored objects provide a robust, efficient cue for indexing into a large database of models, and they can differentiate among a large number of objects.
Journal ArticleDOI
Generalizing the hough transform to detect arbitrary shapes
TL;DR: It is shown how the boundaries of an arbitrary non-analytic shape can be used to construct a mapping between image space and Hough transform space, which makes the generalized Houghtransform a kind of universal transform which can beused to find arbitrarily complex shapes.
Journal ArticleDOI
Predictive coding in the visual cortex: a functional interpretation of some extra-classical receptive-field effects.
Rajesh P. N. Rao,Dana H. Ballard +1 more
TL;DR: Results suggest that rather than being exclusively feedforward phenomena, nonclassical surround effects in the visual cortex may also result from cortico-cortical feedback as a consequence of the visual system using an efficient hierarchical strategy for encoding natural images.
Journal ArticleDOI
Eye movements in natural behavior.
Mary Hayhoe,Dana H. Ballard +1 more
TL;DR: Three separate advances have greatly expanded the understanding of the intricate role of eye movements in cognitive function, especially in neurophysiological studies, and are proving crucial for understanding how behavioral programs control the selection of visual information.
