Perception viewed as an inverse problem
The modern study of perception began when Fechner published his 'Elements of Psychophysics' in 1860. This book has guided most perception research ever since. It has become increasingly clear that there are problems with Fechner's approach, which assumes that the percept is completely determined by the sensory input. Fechner's approach cannot explain the processes that allow our percepts to be ...
متن کاملSurface color perception as an inverse problem in biological vision
The spectral power distribution (SPD) of the light reflected from a matte surface patch in a three-dimensional complex scene depends not only on the surface reflectance of the patch but also on the SPD of the light incident on the patch. When there are multiple light sources in the scene that differ in location, SPD, and spatial extent, the SPD of the incident light depends on the location and ...
متن کاملInitialization of ice-sheet forecasts viewed as an inverse Robin problem
As simulations of 21st-century climate start to include components with longer timescales, such as ice sheets, the initial conditions for those components will become critical to the forecast. This paper describes an algorithm for specifying the initial state of an ice-sheet model, given spatially continuous observations of the surface elevation, the velocity at the surface and the thickness of...
متن کاملPerception Viewed as a Phenotypic Expression
Visual experience relates the optically-specified environment to people’s ever-changing phenotype, which consists of their morphology, physiology, and behavior. Within near space, apparent distances are scaled with morphology, and in particular, to the extent of an actor’s reach. For example, we have found that the apparent distance to targets becomes foreshortened when a person holds a tool, w...
متن کاملPerception as an Inference Problem
Although the idea of thinking of perception as in inference problem goes back to Helmholtz, it is only recently that we have seen the emergence of neural models of perception that embrace this idea. Here I describe why inferential computations are necessary for perception, and how they go beyond traditional computational approaches based on deductive processes such as feature detection and clas...
