If face images are degraded by block averaging, there is a nonlinear decline in recognition
accuracy as block size increases, suggesting that identification requires a critical minimum …

The findings of some of the key studies that have examined the contribution of different
bands of spatial information, specified in terms of cycles per face, to face recognition, and …

The relevance of low and high spatial-frequency information for the recognition of
photographs of faces has been investigated by testing recognition of faces that have been …

It has recently become apparent that if face images are degraded by spatial quantisation, or
block averaging, there is a nonlinear acceleration of the decline in accuracy of recognition …

The purpose of the study was to find out what spatial frequency information human
observers use in the recognition of face images. Signal-to-noise ratio thresholds for the …

A study is reported in which the significance for vision of low-and high-spatial-frequency
components of photographic positive and negative images was investigated by measuring …

Previous research suggests that observers use information near the eyes and eyebrows to
identify both upright and inverted faces [Sekuler, AB, Gaspar, CM, Gold, JM, & Bennett, PJ …

The spatial frequencies most relied upon by subjects in a recall task for face recognition
were found to lie in the midfrequency range. A linear systems analysis model cannot …

Configural relations and a critical band of spatial frequencies (SFs) in the middle range are
particularly important for face recognition. We report the results of four experiments in which …

Contrast sensitivity for face identification was measured as a function of image size to find
out whether foveal and peripheral performance would become equivalent by magnification …
