Visual perception as invariance.
The railroad tracks stretch straight and far away from me over the desert and on to the horizon. I stand squarely between them, looking along them to the horizon, and I observe both that they converge as distance gets greater and also that they are at every distance equidistant. This is the perceptual paradox of converging parallels. Every one has the experience, and Blumenfeld (1, pp. 323-346)...
متن کاملOrientation invariance in visual shape perception.
To assess directly the orientation-invariance of specific shape representation stages in humans, we examined whether rotation (on the image plane or in depth) modulates the conjunction and linear non-separability effects in a shape visual search task (M. Arguin & D. Saumier, 2000; D. Saumier & M. Arguin, 2003). A series of visual search experiments involving simple 2D or 3D shapes show that the...
متن کاملLearning Visual Invariance
Invariance is a necessary feature of a visual system able to recognize real objects in all their possible appearance. It is also the processing step most problematic to understand in biological systems, and most difficult to simulate in computational models. This work investigates the possibility to achieve viewpoint invariance without adopting any explicit theorical solution to the problem, bu...
متن کاملSelectivity and invariance for visual object perception.
The sight of an object triggers a complex set of processes in the brain. Although it is already well established that object perception is performed by a hierarchical network, the so-called ventral visual pathway, we are only starting to understand how neurons along this pathway encode visual information at each processing stage. In this review, we discuss basic principles of neural coding for ...
متن کاملLearning and disrupting invariance in visual recognition
Learning by temporal association rules such as Foldiak’s trace rule [1] is an attractive hypothesis that explains the development of invariance in visual recognition. Consistent with these rules, several recent experiments have shown that invariance can be broken by appropriately altering the visual environment but found puzzling differences in the effects at the psychophysical [2, 3] versus si...
