How Deep is the Feature Analysis underlying Rapid Visual Categorization?

Eberhardt, Sven, Cader, Jonah, Serre, Thomas

Understand

Rapid categorization paradigms have a long history in experimental psychology: Characterized by short presentation times and speedy behavioral responses, these tasks highlight the efficiency with which our visual system processes natural object categories.

  • Previous studies have shown that feed-forward hierarchical models of the visual cortex provide a good fit to human visual decisions.
  • At the same time, recent work in computer vision has demonstrated significant gains in object recognition accuracy with increasingly deep hierarchical architectures.
  • But it is unclear how well these models account for human visual decisions and what they may reveal about the underlying brain processes.
