Journal ArticleDOI
Compulsory averaging of crowded orientation signals in human vision
TL;DR: It is shown that despite their inability to report the orientation of an individual patch, observers can reliably estimate the average orientation, demonstrating that the local orientation signals are combined rather than lost.
Journal ArticleDOI
Visibility of wavelet quantization noise
TL;DR: A mathematical model is constructed for DWT noise detection thresholds that is a function of level, orientation, and display visual resolution that allows calculation of a "perceptually lossless" quantization matrix for which all errors are in theory below the visual threshold.
Journal ArticleDOI
Model of visual contrast gain control and pattern masking
TL;DR: Foley et al. as discussed by the authors implemented a model of contrast gain and control in human vision that incorporates a number of key features, including a contrast sensitivity function, multiple oriented bandpass channels, accelerating nonlinearities, and a devisive inhibitory gain control pool.
Journal ArticleDOI
Texture interactions determine perceived contrast
TL;DR: The results are unanticipated by all current theories of lightness perception and point to a perceptual mechanism for contrast gain control occurring at an early cortical or precortical neural locus.
Journal ArticleDOI
The visual filter mediating letter identification.
TL;DR: It is found that letter-identification and grating-detection filters are identical, showing that the recognition of these objects at one size is mediated and constrained by a single visual filter, or 'channel'.
