    • Various embodiments for components and associated methods that can be used in a binaural speech enhancement system are described. The components can be used, for example, as a pre-processor for a hearing instrument and provide binaural output signals based on binaural sets of spatially distinct input signals that include one or more input signals. The binaural signal processing can be performed by at least one of a binaural spatial noise reduction unit and a perceptual binaural speech enhancement unit. The binaural spatial noise reduction unit performs noise reduction while preferably preserving the binaural cues of the sound sources. The perceptual binaural speech enhancement unit is based on auditory scene analysis and uses acoustic cues to segregate speech components from noise components in the input signals and to enhance the speech components in the binaural output signals.

    • Disclosed is a PTZ video visibility detection method based on luminance characteristic, which includes acquiring a road condition video image by utilizing a PTZ video camera, extracting the region of interest ROI of the road surface to obtain high constancy of selected pixels; acquiring precise road surface region by utilizing region-growing algorism based on Nagao filtering to ensure the illuminance constancy of the selected pixels in world coordinates; in the road surface region, extracting the contrast curve which reflects the luminance variation of the road surface, and searching the feature points of the luminance curve to calculate the human eye distinguishable and maximum far pixels in the image with an extinction coefficient; calculating the maximum visibility distance in combination with camera calibration to determine the visibility value. The present invention can take full advantage of existing PTZ camera to video the road condition and acquire the image without the need of providing any artificial marker. Monitoring can be in real time and has a low monitoring cost, and the monitoring requirement of large area road condition can be satisfied. Monitoring is stable and can not be disturbed by environment. It is a visibility detecting method with the advantages of simpleness, easy realization, high precision and excellent use effect.
