This paper describes the effect of three new acoustic feature parameters to detect audio source segments that are based on spectral cross-correlation: spectral stability, white noise similarity, and sound spectral shape. These parameters are devised for accurate audio source detection and are used in a pre-processing module for automatic indexing of the broadcast news and the meetings. We condu...

Abstract Background Cognitive decline is a common presentation of Parkinson’s disease (PD) and continued search exists for reliable biomarker early identification management this clinical problem. The objective study to select the most useful in assessment PD-related cognitive decline. This cross-sectional included 47 patients with PD matched healthy controls. All participants were assessed by ...

This paper proposes a prototypical environment for gamut mapping in spectral space. Images are rendered in terms of light and material parameters by a symbolic ray tracer, and the parameter ranges are adjusted, without re-rendering, to bring the image into the output device’s spectral gamut. There is a growing disparity between the high dynamic range images produced by spectral renderers and th...

This article introduces mathematical parameters that generalize the frequency distribution of the statistical and spectral model. We show experiments that determine the influence of these parameters on the intensity fluctuations of the synthesized noise, accordingly to the theory developed by psycho-acoustic works. The main goal of these experiments is to be able to analyse and synthesize bands...
