Abstract: A system and method for achieving more accurate results when applying an image processing task to a series of medical images of a patient, without significantly increasing processing resource. The proposed system and method is based on receiving a plurality of image sequences of a particular anatomical region, each capturing cyclical movement of an anatomical object. Each image sequence is supplied to a classifier module which employs use of one or more machine learning algorithms to derive at least one score for each image sequence indicative of predicted success or quality of a result of the image processing task if applied to the given image series. This permits an assessment to be made in advance of which of the plurality of image series is most likely to result in the best (e.g. highest quality, or greatest amount of information) results from the image processing task.

Abstract: In order to realize a correction for changes in the reproduction loudness at low frequencies in a downmix-arrangement, a mixing arrangement is proposed for mixing at least two audio signals, which mixing arrangement is provided with a first unit (104) for deriving a first power signal, which is a measure for the power of the first audio signal, a second unit (105) for deriving a second power signal, which is a measure for the power of the second audio signal, a cross-correlation unit (103) for deriving a cross-correlation signal, which is a measure for a cross-correlation between the first and the second audio signal, a unit (106) for deriving multiplication parameters from the first and second power signals and the cross-correlation signal, and a multiplication and combination unit (107) for carrying out a signal processing on the first and second audio signals and combining them.

Abstract: A method for down-mixing of a m-channel audio signal (L, R, C, Ls, Rs, Rss, Lss) into a n-channel audio signal (Ro, Lo, Rso, Lso), where m is an integer for which holds m>n and n is an integer for which holds n?2, including the step of generating one of the n-channel audio signals of one side (right or left) of a listener (Ro, Lo, Rso, Lso), by a combination of: a first term including a signal component (R, L, Rs, Ls) of the m-channel audio signal of the same side only, and a second term dependent of m, including one or more of further signal components of the m-channel audio signal (C, Ls, Rs, Rss, Lss) of the same side only, multiplied by at least one respective filtering function (H1, H2, H3, H4, H5, H6, H7, H8), said filtering function being dependent on: a frequency characteristic of the transmission path between the position of the loudspeaker of the respective signal component of the further m-channel audio signal, and a position of the right ear or left ear, respectively, of a listener in an m-chan
