A Neuromathematical Model for Geometrical Optical Illusions [PDF]

Journal of Mathematical Imaging and Vision, 2016
Geometrical optical illusions have been object of many studies due to the possibility they offer to understand the behavior of low-level visual processing.

A Computational Study Of The Role Of Spatial Receptive Field Structure In Processing Natural And Non-Natural Scenes [PDF]

, 2018
The center-surround receptive field structure, ubiquitous in the visual system, is hypothesized to be evolutionarily advantageous in image processing tasks.

Judd on Phenomena [PDF]

, 2007
Donald Judd’s 1964 essay 'Specific Objects' probably remains his most well-known. In it, he described new artworks characterized by, among other features, 'a quality as a whole' instead of conventional 'part-by-part structure,' the 'use of three ...

Review of Studies on Visual Perception in Grey Parrots (Psittacus erithacus): The Muller-Lyer Illusion, Amodal and Modal Completion

Animal Behavior and Cognition, 2017
Few avian studies on optical illusions are directly comparable to those with humans. Grey parrots that have some referential use of English speech, however, allow for such comparative studies, as these birds can be tested just as are humans, by asking ...

Exterior optical cloaking and illusions by using active sources: a boundary element perspective

, 2010
Recently, it was demonstrated that active sources can be used to cloak any objects that lie outside the cloaking devices [Phys. Rev. Lett. \textbf{103}, 073901 (2009)].

Notes on Conformal Invisibility Devices [PDF]

, 2006
As a consequence of the wave nature of light, invisibility devices based on isotropic media cannot be perfect. The principal distortions of invisibility are due to reflections and time delays.

The Café Wall Illusion: Local and Global Perception from Multiple Scales to Multiscale

Applied Computational Intelligence and Soft Computing, 2017
Geometrical illusions are a subclass of optical illusions in which the geometrical characteristics of patterns in particular orientations and angles are distorted and misperceived as a result of low-to-high-level retinal/cortical processing.

Whitening toothpaste containing activated charcoal, blue covarine, hydrogen peroxide or microbeads: which one is the most effective?

Journal of Applied Oral Science, 2019
The efficacy of whitening toothpastes is questionable and controversial. Clinicians, patients and researchers have expressed concern with whitening toothpastes due to the risk of wearing the dental structure and the potential for disappointment if the ...

Introspective Training Apprehensively Defended: Reflections on Titchener's Lab Manual [PDF]

, 2004
To study conscious experience we must, to some extent, trust introspective reports; yet introspective reports often do not merit our trust. A century ago, E.B.
