Computer vision systems

A computer vision system potentially offers many benefits over a conventional colour sorter. The ability to simultaneously sort objects on the basis of several different criteria would be a primary advantage. However, for the immediate future, the most likely application of advances in electronic hardware is the gradual improvement in performance of the present generation of sorting machines. [Pg.140]

James Weiland is an associate professor in the Department of Ophthalmology at the Doheny Eye Institute at the University of Southern California. He is interested in technology to assist the blind, and the main focus of his research is an implantable retinal prosthesis. His research group investigates the interface between the retina and the implantable stimulator in order to optimize the visual abilities of patients. They are also developing wearable computer vision systems for aiding blind people. [Pg.148]

In summary, with this book, we have made a step toward a better understanding of a computational theory of color constancy. The main question, which algorithm is used by the human vision system, however, is still unsolved. In the future, noninvasive techniques that help to visualize the workings of the human brain in combination with additional psychophysical experiments may one day lead to the actual algorithm used by the visual system. [Pg.328]

The practices contained in this section apply to all standard instruments, microcontrollers, and smart instrumentation (e g., weigh scales, bar code scanners, controllers, vision systems and EPROM s) considered part of a computer system. This equipment is driven by programmable firmware. [Pg.78]

For a tank suspected of having substantial deposits at the bottom, a fiber-optic camera can be inserted in the tank to provide a view and positive confirmation of the tank bottom condition. These camera and light vision systems are sanitary equipment able to provide a computational real-time visual inspection of the inside tank under process conditions or pressure vessel. In addition, they are used to control several parameters during the manufacturing process, such as product level and thickness, solids level, uniformity of suspensions, foam, and interface and/or cake detection [31]. [Pg.326]

Like humans, most machine vision systems are designed to use shape as the defining characteristic for an object. For these systems then, it is important to make an object s shape as easy to isolate as possible. Both proper illumination of the object and efficient computer processing of the image of that object are necessary. [Pg.185]

The most advanced machine vision systems typically involve acquisition and interpretation of three-dimensional information. These systems often require more sophisticated illumination and processing techniques than one- and two-dimensional systems, but their results can be riveting. These scanners can characterize an object s shape three-dimensionally to tolerances of far less than a millimeter. This allows them to do things such as identify three-dimensional object orientation (important for assembly applications), check for subtle surface deformations in high precision machined parts, and generate detailed surface maps used by computer-controlled machining systems to create clones of the scanned object. [Pg.185]

WhQe GSPT was motivated by needs in situations where the human is the system of interest and it was first presented in this context [Kondraske, 1987a], application of it has been extended to the context of artificial systems. These experiences range from computer vision and sensor fusion [Yen and Kondraske, 1992] to robotics [Kondraske and Standridge, 1988 Kondraske and Khoury, 1992],... [Pg.1225]

Methods based in traditional competitive learning are focused on data density representation to be optimal from the point of view of reducing the Shannon s information entropy for the use of codewords in a transmission task. However it is not always desirable a codebook representation with direct proportion between its codeword density and the data density. For example, in the human vision system, the attention is attracted to visually salient stimuli, and therefore only scene locations sufficiently different from their surroundings are processed in detail. A simple framework to think about how Saliency may be computed in biological brains has been developed over the past three decades [10,19]. [Pg.213]
