Does Face Image Statistics Predict a Preferred Spatial Frequency for Human Face Processing?
Matthias S. Keil
Psychophysical experiments suggested a relative importance of a narrow band of spatial frequencies for recognition of face identity in humans. There exists, however, no conclusive…

Gradient Representations and the Perception of Luminosity
Matthias S. Keil
The neuronal mechanisms that serve to distinguish between light-emitting and light reflecting objects are largely unknown. It has been suggested that luminosity perception implemen…

Face Recognition in the Machine Reveals Properties of Human Face Recognition
Matthias S. Keil, Agata Lapedriza, David Masip +1
Psychophysical studies suggest that face recognition takes place in a narrow band of low spatial frequencies (``critical band''). Here, we examined the recognition performance of a…
