Significance of Natural Scene Statistics in Understanding the Anisotropies of Perceptual Filling-in at the Blind Spot
Rajani Raman, Sandip Sarkar
Psychophysical experiments reveal our horizontal preference in perceptual filling-in at the blind spot. On the other hand, vertical preference is exhibited in the case of tolerance…
Predictive coding: A Possible Explanation of Filling-in at the blind spot
Rajani Raman, Sandip Sarkar
Filling-in at the blind-spot is a perceptual phenomenon in which the visual system fills the informational void, which arises due to the absence of retinal input corresponding to t…
A Possible Model of Noise Enhanced Visual Perception in Human Vision
Ajanta Kundu, Sandip Sarkar
We demonstrate, through simulation, that a simple centre surround receptive field of vision is capable of exhibiting stochastic resonance. We also show that this could be used to m…
Can Centre Surround Model Explain the Enhancement of Visual Perception through Stochastic Resonance?
Ajanta Kundu, Sandip Sarkar
We demonstrate the ability of centre surround model for simulating the enhancement of contrast sensitivity through stochastic resonance observed in psychophysical experiments. We a…
Laser Actuated Presentation System
Atul Chowdhary, Vivek Agrawal, Subhajit Karmakar +1
We present here a pattern sensitive PowerPoint presentation scheme. The presentation is actuated by simple patterns drawn on the presentation screen by a laser pointer. A specific…
A possible low-level explanation of "temporal dynamics of brightness induction and White's illusion"
Subhajit Karmakar, Sandip Sarkar
Based upon physiological observation on time dependent orientation selectivity in the cells of macaque's primary visual cortex together with the psychophysical studies on the tunin…
