Abstract: The present invention relates to a device and a corresponding method for audible transient noise detection in an audio signal. To avoid the detection of false positives or at least reduce the number of detected false positives a device is proposed comprising a detector configured to detect a set of transient noise candidates in time or frequency domain among a plurality of samples of said audio signal, and a selector configured to select audible transient noise candidates from said set of transient noise candidates by use of one or more selection criteria, wherein the selection criteria used for said selection are selected and/or whose parameters are at least partly set based on characteristics of said audio signal.

Abstract: A method and apparatus for estimating a disparity distribution between a left image and a right image of a stereoscopic 3D picture, each image having an array of pixels, including: providing a maximum range of disparity; correlating, by an estimation device, a left image area with a right image area, with one of both image areas being shifted by a disparity shift value, wherein the result of the correlation is an indication of a pixel match between both images; repeating the correlating for a set of disparity shift values within the maximum range of disparity; and deriving the disparity distribution from the results of the correlation.
