Abstract: A door unlocking and/or door opening mechanism may have an actuating device that may have at least one actuating element, a housing, and at least one detection unit. The detection unit may have a sensor, a trigger element and an evaluation unit. The detection unit may be arranged in the housing. The actuating element may be arranged for an actuation outside the housing and in a region that is accessible from the outside. The trigger element may be arranged at a distance from the sensor in a locked state of the door unlocking and/or door opening mechanism. When the actuating element is actuated in the direction of the housing, to the actuating element deforms the trigger element. The sensor detects a change in the distance between the trigger element and the sensor.

Abstract: A method for checking the plausibility of an initially known transverse movement of an object. The method includes: emission of a radar signal having constant signal frequency, and reception by a radar device of reflections of the radar signal having constant signal frequency; and checking the plausibility of the transverse movement of the object by analyzing frequency ranges corresponding to the transverse movement in a spectrum of the reflected radar signal having constant signal frequency.

Abstract: A method for detecting misalignment of a radar sensor positioned on a vehicle. A Doppler spectrum for the radiation emitted and received by the radar sensor is ascertained. For at least one frequency bin of the Doppler spectrum, an angle of incidence is determined in at least a subinterval. The determined angle of incidence is compared to the angle of incidence expected for the frequency bin. A misalignment of the radar sensor is detected as a function of the difference of the measured angle of incidence from the expected angle of incidence.

Abstract: A method and an apparatus for removing outliers from a main view of a scene during 3D reconstruction of a scene from multiple views of the scene. A 3D projection unit projects a 3D point of a pixel of the main view into neighboring views. A comparator then compares the distance of each of the projected 3D points in the neighboring views to the 3D point of the main view with a defined distance threshold. Based on the comparison a flagging unit assigns flags to the pixel in the main view. Finally, depending on values of the flags a rejecting unit rejects the pixel in the main view as an outlier.

Abstract: The invention relates to a method and an apparatus for determining a disparity value for an object located in or to be placed into a stereoscopic image pair having an associated disparity map. First an area to be analyzed in one of the stereoscopic images is determined Then a histogram is built from disparity estimates of the associated disparity map that fall within the determined area. Subsequently a contiguous range of bins is searched in the histogram that also contains a sufficient number of pixels. Finally, a disparity estimate for the determined area is selected from the contiguous range of histogram bins.

An eye blink of a creature that is imaged in the video content is detected. The temporal synchronization mismatch is determined by determination of a temporal offset between the reproduction of an eye blink in the first video stream and the reproduction of said eye blink in the second video stream.

The apparatus comprises a parameter retrieving unit that retrieves an initial image comprising pixels with pure foreground colors or pure background colors from the input image and pixels with initial color estimates, e.g. from a color estimator or by resorting to a previously generated initial image. A guided image filter then filters the initial image using the input image as a guiding image.
