<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Arial">We will describe a class of quantitative models of the ventral stream for object recognition, which have been developed during the last two decades from the anatomical and physiological data and which are quite successful in explaining several physiological data across different visual areas. Surprisingly, such models also mimic the level of human performance in difficult rapid image categorization tasks in which human vision is forced to operate in a feedforward mode. The main focus of the talk will be on extending these hierarchical models to deal with recognition in image sequences and to account for computational roles of attention and cortical backprojections.</FONT></SPAN></P>
<P DIR=LTR><SPAN LANG="en-us"><FONT FACE="Arial">Finally we will also sketch initial steps with S. Smale, J. Bouvrie and L. Rosasco towards a mathematical theory of hierarchical architectures described by the models of visual cortex.</FONT></SPAN></P>
