Abstract: A method for evaluating images and, in particular, for evaluating correspondence hypotheses of images. The method includes (i) providing a hypothesis matrix of correspondence hypotheses between first and second images, each given as a corresponding image matrix, (ii) evaluating the hypothesis matrix and conditional verification of the image correspondence hypotheses and (iii) providing verified image correspondence hypotheses in a correspondence matrix of image correspondences as the evaluation result, the hypothesis matrix being evaluated by forming and evaluating a histogram with respect to the values of the component for each element of the hypothesis matrix for at least one component of correspondence hypotheses.

Abstract: A method for ascertaining/mapping between a matrix element (ME) and a comparison ME (CME) of a comparison matrix (CM), including writing the ME position in a table element (TE) of a correspondence table (CT) for a number of MEs, and following a predefined offset, reading out a TE, ascertaining the ME position stored in the TE until the read for the same number of MEs has been performed, establishing a mapping from the TE's read-out position and a CME's current position. The writing includes reading out a ME feature, ascertaining an access feature (AF) from the ME feature, ascertaining a TE of the CT from the AF, and writing the ME position in the ascertained TE. The reading includes reading out a CME feature, ascertaining an AF from the CME, ascertaining a TE of the CT from the AF, and reading out the ME's stored position from the ascertained TE.

Abstract: A method for evaluating images and in particular for evaluating correspondences of images. The method includes (i) providing correspondences between given first and second images, (ii) providing a quality measure or a plurality of quality measures as attributes for characterizing a particular correspondence, (iii) evaluating and conditionally selecting the correspondences, (iv) providing selected correspondences as an evaluation result, the evaluation of correspondences being based on a combination of attributes and the selection of correspondences being based on a result of the evaluation.

Abstract: A method for lossy compression of measured data obtained through physical observation of a detection area. The method includes: the measured data and/or data prepared therefrom are divided with respect to at least one criterion into a plurality of classes and/or regions; the classes and/or regions are assigned priorities with respect to the intended evaluation of the measured data or to the data prepared therefrom; temporal changes of the measured data and/or of the data prepared therefrom divided into each class or region are compressed in a lossy manner, the degree of compression being a function of the priority assigned to the class or region. A method for monitoring a vehicle driving in traffic, and/or for controlling a vehicle driving at least in a semi-automated manner in traffic using the method for lossy compression, a compression module, camera, radar module or LIDAR module, and computer program, are also described.

Abstract: A radar sensor including an antenna array having multiple antenna elements situated next to one another and at least one feeding point at an outer antenna element. The antenna elements are connected in series via delay lines. The radar sensor has at least two transmitting and receiving units which are each suitable for generating and evaluating a radar signal at a predefined frequency. The at least two transmitting and receiving units are connected to a feeding point of the antenna array. The frequencies of the radar signals of the at least two transmitting and receiving units are predefinable independently of one another.

Abstract: An antenna has an antenna body having a plurality of first antenna elements, which are disposed along a first straight line. A hollow conductor, which extends between the first antenna elements, is disposed in the antenna body. The first antenna elements are developed as openings running between the hollow conductor and a surface of the antenna body. The antenna is designed to radiate a signal in a spatial direction that is a function of a frequency of the signal. The antenna body has an electrically insulating material that is coated with a conductive material.

Abstract: An antenna has an antenna body having a plurality of first antenna elements situated along a first straight line. The antenna body includes a first conductive grounded surface and a second conductive grounded surface, the first and second grounded surfaces being situated essentially parallel to one another. A dielectric is situated between the first and second grounded surfaces. A signal conductor is also situated between the first and second grounded surfaces. The first antenna elements are designed as apertures situated above the signal conductor in the first grounded surface. Furthermore, the antenna is designed to emit a signal in a direction in space, depending on a frequency of the signal. At least two of the first antenna elements differ from one another in such a way that their power emissions are different.

Abstract: In a method for the dynamic assignment of resources in a communication system, a cyclical time frame of at least intermittently fixed temporal duration is predefined for the access of communication participants, time slots in the time frame being assigned to the communication participants. The duration of unused time slots is shortened, which means that additional time slots are able to be accommodated in the time frame, which are assigned to communication participants dynamically, in particular as a function of their communication requirements.
