    摘要： A device for identifying characters in an image comprises a Hough transformer which is designed to identify circular or elliptical arcs in the image or in a pre-edited version of the image as identified elements of script. The device also comprises a character description producer which is designed to obtain, using the identified circular or elliptical arcs, a character description that describes a position of the identified circular or elliptical arcs. The device further comprises a database comparator which is designed to compare the character description with a plurality of comparative character descriptions which are associated with character codes in order to yield a character code of an identified character as the result of comparison.

    摘要： A device for producing a filtered activity pattern (146), which is based on a first activity pattern (110) on a hearing model of a first ear and a second activity pattern (112) on a hearing model of a second ear, comprises an identifier (120) for identifying a first trajectory in the first activity pattern and a second trajectory in the second activity pattern, which are associated with the same sound event. The device (100) furthermore comprises a determinator (130) for determining whether the two trajectories are associated with a sound event of a wanted sound source. The device furthermore comprises a filter (140) for filtering the first activity pattern or the second activity pattern based on a result of the determinator as to whether a trajectory is associated with a sound event of the wanted sound source, so that in the filtered activity pattern activity events that are associated with a sound event of the wanted sound source dominate, or that the activity events which are not associated with a sound event of the wanted sound source are no longer present in the filtered activity pattern. The described device can additionally be used to implement a source separator. The device according to the invention enables a determination of a filter activity pattern in an efficient, reliable and hearing-adjusted manner, so that in the filtered activity pattern a wanted sound source is emphasized, while interference sound sources are suppressed or damped.

    摘要： The invention relates to a method for extracting a signal identifier from a time signal, according to which the temporal occurrence of signal edges is detected in the time signal (12), whereby a signal edge has a specified temporal length. In addition, the temporal interval between two selected detected signal edges is determined (14). A frequency value is calculated (16) from said determined interval and is assigned to a time of occurrence of the frequency value in the time signal in order to obtain a co-ordinate tuple from the frequency value and the time of occurrence for said frequency value. A signal identifier is created from a plurality of co-ordinate tuples (18), each co-ordinate tuple containing a frequency value and a time of occurrence, in such a way that the signal identifier comprises a sequence of signal identifier values, which reproduce the temporal course of the time signal. The extracted signal identifier is based on signal edges of the time signal and reproduces the temporal course of the time signal. The signal identifier thus characterises the time signal and is stable in relation to changes to said time signal.
