Overview of Mine Fire Detection

By: John C, Edwards

Several experimental programs were conducted at the Pittsburgh Research Center to investigate the level of mine fire detection and alarm capability possible using state-of-the-art technology. These programs involved comparison of the response and alarm time of optical and ionization type smoke sensors to smoldering and flaming coal combustion in a smoke chamber. Coal combustion experiments conducted in the smoke chamber demonstrated that a CO concentration of 5 ppm above...

Very Low Bit Rate Wavelet-Based Scalable Video Compression

By: Eduardo Asbun

Government Reference Publication

Excerpt: Rate scalable video compression is appealing for low bit rate applications, such as video telephony and wireless communication, where bandwidth available to an application cannot be guaranteed. A technique known as Scalable Adaptive Motion Compensated Wavelet (SAMCoW) compression is described in this paper. SAMCoW is well suited for data rates less than 32 kbps. Several techniques to improve the subjective picture quality of SAMCoW are investigated. These includ...

Levels of Disease Diagnosis

By: Food and Agriculture Organization of the United Nations

Nutrition Reference Publication

Excerpt: The accurate diagnosis of aquatic animal diseases requires different levels of disease surveillance and data collection, ranging from farm-site observations through to the use of state-of-the-art diagnostic technology. Development of expertise at each level of diagnosis requires investment in training and infrastructure, with successive levels requiring more complex training and greater financial resources. Table 6.1 shows the investment required at the three di...

Real Time Computer Surveillance for Crime Detection

By: Larry S. Davis

Government Reference Publication

Excerpt: Chapter 1 - Introduction The Computer Vision Laboratory at the University of Maryland has been designing and developing real time computer vision algorithms for visual surveillance systems. A visual surveillance system must be able to detect and track people under a wide variety of environmental and imaging conditions, and then must analyze their actions and interactions with one another and with objects in their environment to determine when “alerts” should be ...

Integrated Approach of Multiple Face Detection for Video Surveillance

By: Tae Kyun Kim and Sung U.K. Lee

Government Reference Publication

Excerpt: For applications such as video surveillance and human computer interface, we propose an efficiently integrated method to detect and track faces. Various visualcues are combined to the algorithm: motion, skin color, global appearance and facialpat tern detection. The ICA (Independent Component Analysis)-SVM (Support Vector Machine) based pattern detection is performed on the candidate region extracted by motion, color and global appearance information. Simultaneo...

By: Stephen Nesnow

Government Reference Publication

Excerpt: Structure-activity analysis is a powerful tool to study the relationship between chemicals and their biological effects. The elucidation of specific chemical features that directly or indirectly result in the expression of a biochemical or biological change can provide new insights into the mechanisms of action of the chemicals as well as the structure and function of the biological system. We have previously reported on the development of an innovative genetic ...

By: Victoria Mcgovern

Government Reference Publication

Excerpt: There are tradeoffs to enjoying ones day in the sun. The obvious pleasures of outdoor recreation come at the cost of accelerated aging of the skin, formation of cataracts and other damage to the eyes, and increased risk of skin cancers. The deadliest of the skin cancers, melanoma, has been specifically tied to recreational exposure, as during summertime sunbathing and gardening. Although fatal when allowed to spread, melanoma is easily treated when diagnosed ear...

Pattern Recognition Methods for Object Boundary Detection

By: Arnaldo J. Abrantesy

Government Reference Publication

Excerpt: Boundary extraction is a data representation problem: image features are segmented and approximated by a parametric curve or a sequence of model points. However, the use of classic Pattern Recognition methods in boundary detection is unusual when compared with more popular approaches, e.g., active contours. This can be partially explained by their inability to separate boundary edges from other image strokes. This paper presents modified versions of several clus...
