Resumo(s)
In this paper we present an improved scheme for line and edge detection in cortical area V1, based on responses
of simple and complex cells, truly multi-scale with no free parameters. We illustrate the multi-scale
representation for visual reconstruction, and show how object segregation can be achieved with coarse-to-finescale
groupings. A two-level object categorization scenario is tested in which pre-categorization is based on
coarse scales only, and final categorization on coarse plus fine scales. Processing schemes are discussed in the
framework of a complete cortical architecture.
