Learning Generic Invariances in Object Recognition: Translation and Scale
(2010-12-30)
Invariance to various transformations is key to object recognition but existing definitions of invariance are somewhat confusing while discussions of invariance are often confused. In this report, we provide an operational ...
Scene Classification with a Biologically Inspired Method
(2009-05-10)
We present a biologically motivated method for scene image classification. The core of the method is to use shape based image property that is provided by a hierarchical feedforward model of the visual cortex [18]. Edge ...
Werner Reichardt: the man and his scientific legacy
(2011-03-04)
Excerpts from a talk given by Tomaso Poggio in Tübingen on the opening ofthe Werner Reichardt Centrun für Integrative Neurowissenschaften, December 8, 2008.
On the difficulty of feature-based attentional modulations in visual object recognition: A modeling study.
(2004-01-14)
Numerous psychophysical experiments have shown an important role for attentional modulations in vision. Behaviorally, allocation of attention can improve performance in object detection and recognition tasks. At the neural ...
From primal templates to invariant recognition
(2010-12-04)
We can immediately recognize novel objects seen only once before -- in different positions on the retina and at different scales (distances). Is this ability hardwired by our genes or learned during development -- and ...
