Does face image statistics predict a preferred spatial frequency for human face processing? by Keil, Matthias S

“…Psychophysical experiments suggested a relative importance of a narrow band of spatial frequencies for recognition of face identity in humans. There exists,…”

Dendritic Pooling of Noisy Threshold Processes Can Explain Many Properties of a Collision-Sensitive Visual Neuron by Keil, Matthias S

“…Power laws describe brain functions at many levels (from biophysics to psychophysics). It is therefore possible that they are generated by similar underlying…”

People favour imperfect catching by assuming a stable world by López-Moliner, Joan, Keil, Matthias S

“…The visual angle that is projected by an object (e.g. a ball) on the retina depends on the object's size and distance. Without further information, however,…”

A calcium-influx-dependent plasticity model exhibiting multiple STDP curves by Houben, Akke Mats, Keil, Matthias S.

“…Hebbian plasticity means that if the firing of two neurons is correlated, then their connection is strengthened. Conversely, uncorrelated firing causes a…”

Preferred spatial frequencies for human face processing are associated with optimal class discrimination in the machine by Keil, Matthias S, Lapedriza, Agata, Masip, David, Vitria, Jordi

“…Psychophysical studies suggest that humans preferentially use a narrow band of low spatial frequencies for face recognition. Here we asked whether artificial…”

Luminance gradients and non-gradients as a cue for distinguishing reflectance and illumination in achromatic images: A computational approach by Lerer, Alejandro, Supèr, Hans, Keil, Matthias S.

“…The brain analyses the visual world through the luminance patterns that reach the retina. Formally, luminance (as measured by the retina) is the product of…”
