Biologically-inspired characterization of sparseness in natural images
Laurent U Perrinet
Natural images follow statistics inherited by the structure of our physical (visual) environment. In particular, a prominent facet of this structure is that images can be described…
Sparse models for Computer Vision
Laurent Perrinet
The representation of images in the brain is known to be sparse. That is, as neural activity is recorded in a visual area ---for instance the primary visual cortex of primates--- o…
Visual motion processing and human tracking behavior
Anna Montagnini, Laurent Perrinet, Guillaume S Masson
The accurate visual tracking of a moving object is a human fundamental skill that allows to reduce the relative slip and instability of the object's image on the retina, thus grant…
Testing the Odds of Inherent versus Observed Over-dispersion in Neural Spike Counts Odds of Inherent versus Observed Over-dispersion
Wahiba Taouali, Giacomo Benvenuti, Pascal Wallisch +2
The repeated presentation of an identical visual stimulus in the receptive field of a neuron may evoke different spiking patterns at each trial. Probabilistic methods are essential…
Active inference, eye movements and oculomotor delays
Laurent Perrinet, Rick Adams, Karl Friston
This paper considers the problem of sensorimotor delays in the optimal control of (smooth) eye movements under uncertainty. Specifically, we consider delays in the visuo-oculomotor…
State-dependent changes of connectivity patterns and functional brain network topology in Autism Spectrum Disorder
Pablo Barttfeld, Bruno Wicker, Sebastián Cukier +4
Anatomical and functional brain studies have converged to the hypothesis that Autism Spectrum Disorders (ASD) are associated with atypical connectivity. Using a modified resting-st…
