Vision without Inversion of the Retinal
Seventh Day.—In the morning the flow of ideas while I was blindfolded was like that described for the evening before. But I noticed in bathing that the old representation of those parts of my body which I had so frequently seen ( at least in their clothing) during the experiment, was decidedly less vivid, the outline more blurred, the color paler, grayer, more ' washed out,' than of the parts w...
متن کاملT H E Psychological Review . Vision without Inversion of the Retinal Image
In the November number of this REVIEW, I gave a short account of some preliminary experiments on vision without inversion of the retinal image. Brief as the experiments were, they gave certain definite results and hinted at others which would probably be obtained if the artificial conditions were continued for a longer time. The course of the experience also showed that problems much wider than...
متن کاملSome Preliminary Experiments on Vision without Inversion of the Retinal Image
Two important theories of upright vision hold that the inversion of the retinal image is necessary for the perception of things as upright. According to the first, which we may call the projection theory, objects are projected back into space in the directions in which the rays of light fall upon the retina. And the crossing of these lines of direction within the eye requires that if the object...
متن کاملVision without the Image
Novel image sensors transduce the stream of photons directly into asynchronous electrical pulses, rather than forming an image. Classical approaches to vision start from a good quality image and therefore it is tempting to consider image reconstruction as a first step to image analysis. We propose that, instead, one should focus on the task at hand (e.g., detection, tracking or control) and des...
متن کاملLASERS WITHOUT INVERSION: DENSITY OPERATOR METHOD
A quantum theory of a two and three-level laser with injected atomic coherence is developed by using a density operator method, to the best of our knowledge, for the first time. The initial atomic coherence plays an essential role. At steady state, the equation of motion for the density operator yields to exhibit laser without inversion and a phase locking but no threshold for the laser fie...
