Self-attention in Vision Transformers Performs Perceptual Grouping, Not Attention
Paria Mehrani, John K. Tsotsos
Recently, a considerable number of studies in computer vision involves deep neural architectures called vision transformers. Visual processing in these models incorporates computat…
Learning a model of shape selectivity in V4 cells reveals shape encoding mechanisms in the brain
Paria Mehrani, John K. Tsotsos
The mechanisms involved in transforming early visual signals to curvature representations in V4 are unknown. We propose a hierarchical model that reveals V1/V2 encodings that are e…
Multiplicative modulations in hue-selective cells enhance unique hue representation
Paria Mehrani, Andrei Mouraviev, John K. Tsotsos
There is still much to understand about the color processing mechanisms in the brain and the transformation from cone-opponent representations to perceptual hues. Moreover, it is u…
Early recurrence enables figure border ownership
Paria Mehrani, John K. Tsotsos
The face-vase illusion introduced by Rubin demonstrates how one can switch back and forth between two different interpretations depending on how the figure outlines are assigned [1…
Color-opponent mechanisms for local hue encoding in a hierarchical framework
Paria Mehrani, Andrei Mouraviev, Oscar J. Avella Gonzalez +1
A biologically plausible computational model for color representation is introduced. We present a mechanistic hierarchical model of neurons that not only successfully encodes local…
