How many categories can you recognize? Currently the best estimate is due to Irv Biederman: 3000 entry-level categories and perhaps 3*104 categories overall. This estimate was obtained indirectly, by counting words in a dictionary. I will present a method to obtain a direct estimate. Alongside the estimate one gets frequencies of objects and categories for free. I will discuss the implications for visual recognition and other visual problems.
