Welcome!

The First Workshop on Fine-Grained Visual Categorization was held on June 25th, 2011 in conjunction with the CVPR 2011 conference.

Workshop Description

Fine categorization, for example the fine distinction into species of animals and plants, of car and motorcycle models, of architectural styles, etc., is one of the most interesting and useful open problems that the machine vision community has yet to confront. Aspects of fine categorization (also referred to as "subordinate categorization" in the psychology literature) are discrimination of related categories, taxonomization, and discriminative vs. generative learning.

Fine categorization lies in the continuum between basic level categorization (frog vs piano) and identification of individuals (face recognition, biometrics).  The visual distinctions between similar categories are often quite subtle and therefore difficult to address with today’s general-purpose object recognition machinery.  It is likely that radical re-thinking of some of the matching and learning algorithms and models that are currently used for visual recognition will be needed to approach fine categorization.

This workshop will explore computational questions of modeling, learning, detection and localization.  The invited talks, including researchers from psychology and psychophysics, will shed light on human expertise and human performance in subordinate categorization and taxonomization.
