We investigate the role of sparsity and localized features in a biologically-inspired model of visual object classification. As in the model of Serre, Wolf, and Poggio, we first a...

The appearance of an object is composed of local structure. This local structure can be described and characterized by a vector of local features measured by local operators such a...
