The flash-lag effect as a motion-based predictive shift

MA Khoei, GS Masson, LU Perrinet - PLoS computational biology, 2017 - journals.plos.org
Due to its inherent neural delays, the visual system has an outdated access to sensory
information about the current position of moving objects. In contrast, living organisms are …

Cortical recurrence supports resilience to sensory variance in the primary visual cortex

HJ Ladret, N Cortes, L Ikan, F Chavane… - Communications …, 2023 - nature.com
Our daily endeavors occur in a complex visual environment, whose intrinsic variability

Speed-selectivity in retinal ganglion cells is sharpened by broad spatial frequency, naturalistic stimuli

CR Ravello, LU Perrinet, MJ Escobar, AG Palacios - Scientific reports, 2019 - nature.com
Motion detection represents one of the critical tasks of the visual system and has motivated a
large body of research. However, it remains unclear precisely why the response of retinal …

A normalization mechanism for estimating visual motion across speeds and scales

N Gekas, AI Meso, GS Masson, P Mamassian - Current Biology, 2017 - cell.com

consequences of a dynamic process relying on optimal inference with respect to a …

Skewed alpha-stable distribution for natural texture modeling and segmentation in contourlet domain

K Sarafrazi, M Yazdi - Eurasip Journal on Image and Video Processing, 2019 - Springer
Texture modeling is a very useful tool in image analysis. This model can be used in texture
segmentation, denoising or texture synthesis. In this work, alpha-stable distribution has been …

Biologically-inspired characterization of sparseness in natural images

LU Perrinet - 2016 6th European Workshop on Visual …, 2016 - ieeexplore.ieee.org
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 …
