Demosaicing is the process by which from a single CCD sensor measuring only one color component per pixel, red, green or blue, one can infer a fully color information at each pixel. This inference involves a deep understanding of the interaction between colors and the involvement of local geometry. Although quite successful in making such inferences with very small relative error, state of the ...

A highly desirable possible application of simulation of auditory scene analysis is the development of hearing aids capable of suppressing disturbing sound sources in complex noise environments. It is well-known that in such situations spatial cues contribute a small, but often decisive hint for auditory scene analysis. Concerning noise suppression, they have the interesting advantage that they...

Hearing impaired professional musicians or industrial workers often report that they were able to identify mistuned chords in a music piece or even slight changes in the noise of their machines (usually > 100 dB SPL) though they were handicapped in listening tasks in daily routine. In order to assess central processing of acoustic stimuli, we analyzed auditory evoked potentials (AEP) and EEG sp...

Previous studies on the question of noise in hospitals have been based on the replies of patients to questionnaires. This paper records what is to our knowledge the first attempt to determine sound levels in a hospital by direct measurement; the work was carried out in the Bristol Royal Infirmary. Some justification is needed for the use of objective sound measurement. Admittedly the intensity ...

The efficient generation of high-fidelity entangled states is the key element for long-distance quantum communication, computation and other technologies, at same time most resource-consuming part in many schemes. We present a new class entanglement-assisted entanglement purification protocols that can generate from noisy, finite-size ensembles with improved yield fidelity as compared to previo...

Ensemble methods take their output from a set of base predictors. The ensemble accuracy depends on two factors: the base classifiers accuracy and their diversity (how different are these base classifiers outputs from each other). An approach for increasing the diversity of the base classifiers is presented in this paper. The method builds some new features to be added to the base classifier tra...

A n epidemic of neurobehavioral problems is sweeping through children today. According to In Harm s Way: Toxic Threats to Child Development, a May 2000 report published by the Greater Boston Physicians for Social Responsibility, 12 million American children suffer from learning, developmental, or behavioral disabilities. Specifically, these disabilities may include attention-deficit/hyperactivi...

Traffic sign recognition is a difficult task if we aim at detecting and recognizing signs in images captured from unfavorable environments. Complex background, weather, shadow, and other lighting-related problems may make it difficult to detect and recognize signs in the rural as well as the urban areas. We employ discrete cosine transform and singular value decomposition for extracting feature...

Reconfigurable systems have benefited of the novel partial dynamic reconfiguration features of recent FPGA devices. Enabling the concurrent reconfiguration without disturbing system operation, this technology has raised a new test challenge: to assure a continuously fault free operation, independently of the circuit present after many reconfiguration processes, testing the FPGA without disturbi...
