Abstract:
Many of the lower-level areas in the mammalian visual system are
organized retinotopically, that is, as maps which preserve to a
certain degree the topography of the retina. A unit that is a part
of such a retinotopic map normally responds selectively to
stimulation in a well-delimited part of the visual field, referred
to as its receptive field (RF). Receptive fields are probably
the most prominent and ubiquitous computational mechanism employed
by biological information processing systems. This paper surveys
some of the possible computational reasons behind the ubiquity of
RFs, by discussing examples of RF-based solutions to problems in
vision, from spatial acuity, through sensory coding, to object
recognition.
