CBF: A New Framework for Object Categorization in Cortex

Building on our recent hierarchical model of object recognition in cortex, we show how this model can be extended in a straightforward fashion to perform basic-level object categorization. We demonstrate the capability of our scheme, called “Categorical Basis Functions” (CBF) with the example domain of cat/dog categorization, using stimuli generated with a novel 3D morphing system. We also contrast CBF to other schemes for object categorization in cortex, and present preliminary results from a physiology experiment that support CBF.
