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 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 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 کاملPerception of Transformation-Invariance in the Visual Pathway
Visual perception of transformation invariance, such as translation, rotation and scaling, is one of the important functions of processing visual information in the Brain. To simulate this perception property, we propose a computational model for perception of transformation. First, we briefly introduce the transformation-invariant basis functions learned from natural scenes using Independent C...
متن کاملVisual Observables and Invariance
This paper presents the visual measurement of physical object properties that characterize the perceived object including: size, shape, surface properties, cover reflectance properties, distance, and motion. We provide an overview of complete set of local spatial, spectral and temporal measurements. From local visual measurements and a physical model of the visual stimulus formation, we derive ...
