Visual Anagrams: Generating Multi-View Optical Illusions with Diffusion Models [PDF]

open access: yesComputer Vision and Pattern Recognition, 2023
We address the problem of synthesizing multi-view optical illusions: images that change appearance upon a transformation, such as a flip or rotation. We propose a simple, zero-shot method for obtaining these illusions from off-the-shelf text-to-image ...

Edges and gradients in lightness illusions: Role of optical veiling glare

open access: yesFrontiers in Psychology, 2022
Lightness Illusions (Contrast, Assimilation, and Natural Scenes with Edges and Gradients) show that appearances do not correlate with the light sent from the scene to the eye.

Variational Principle and Diverse Wave Structures of the Modified Benjamin-Bona-Mahony Equation Arising in the Optical Illusions Field

open access: yesAxioms, 2022
This study focuses on investigating the modified Benjamin-Bona-Mahony equation that is used to model the long wave in nonlinear dispersive media of the optical illusion field.

An optical illusion. [PDF]

open access: yesScience, 1896
WHILE doing some photographic work with a light from a Welsbach burner, which shone through a small ground glass window in a dark-room, I noticed that when a lamp emitting red rays from its vertical sides was placed in a position so that its top was illuminated by the white light from the window, and while in this light it was then moved by hand to and

Percezioni, ragionamenti e illusioni

open access: yesRivista di Estetica, 2015
Common sense tends to believe in the existence of optical and perceptual illusions but it hardly supports the thesis of an illusory reasoning. In the psychology of reasoning, one rather talks of errors of reasoning that experience can fix and change. For

Computing optical flow in the primate visual system [PDF]

open access: yes, 1989
Computing motion on the basis of the time-varying image intensity is a difficult problem for both artificial and biological vision systems. We show how gradient models, a well-known class of motion algorithms, can be implemented within the magnocellular ...

Ilusi Optis dalam Dunia Seni dan Desain

open access: yesHumaniora, 2012
Visual is everything to do with vision. The ability of our brain to interpret visual is what we call visual perception. In the development of art and design, many artists and designers study visual perception and embody it in their works.

Illusionists [PDF]

open access: yesi-Perception, 2014
Illusions have been displayed in art for millennia but they were not addressed seriously by visual science until the mid-nineteenth century when Johann Joseph Oppel referred to the small spatial distortions as ‘geometrical optical illusions’. Many of the
