Abstract: A method is provided for pressure equalization when shutting a vehicle door or tailgate, wherein the door or tailgate is designed to close an opening into a vehicle interior, in particular to enable loading or unloading or entering or exiting. An airflow can be conveyed into the vehicle interior from outside the motor vehicle interior through an air inlet opening via an air inlet system. The air inlet opening can be closed via a closure device. The method detects a vehicle standstill mode; detects an opened vehicle door or tailgate; controls the closure device of the air inlet opening; and opens the air inlet opening.

Abstract: A door system is provided for a passenger vehicle having at least two seat rows. The door system includes a front side door of a corresponding vehicle side, which can be brought into an open position from a closed position in order to take a seat in the rear seat row or to leave the rear seat row. In order to create a door system by which easier and more comfortable closing of the front side door is enabled, the front side door can be moved from the open position into the closed position by a door drive.

Abstract: A method for analyzing a program may include obtaining the program and obtaining a points-to analysis that may include points-to tuples. The method may further include obtaining a result of a query based on the program. The method may further include extracting a data-flow trace specification that includes flow tuples. Each flow tuple may include a source variable defined in a first method and a sink variable defined in a second method. The method may further include adding, in a recursive manner until a termination condition is triggered, a trace edge to a data-flow trace graph for each points-to tuple of a list of points-to tuples. The respective points-to tuple and a first flow tuple may be used to form a first points-to tuple that is added to the list of points-to tuples. The list of points-to tuples may be initialized to the result of the query.

Abstract: An intrusion detection method, system and computer-readable media are disclosed. The system can include a processor programmed to perform computer network intrusion detection. The intrusion detection can include an identification module and a detection module. The identification module can be adapted to perform semi-supervised machine learning to identify key components of a network attack and develop MDL models representing those attack components. The detection module can cluster the MDL models and use the clustered MDL models to classify network activity and detect polymorphic or zero-day attacks.

Abstract: A method for acquiring a 3D image dataset for an image object based on a plurality of 2D image datasets relating to the image object is proposed. A scattered radiation is taken into account in an acquisition operator used in the method for the optimum reconstruction of the 3D image dataset. The acquisition operator should be as close as possible to the real mapping operator.

Abstract: An interpolation of data values is performed during the acquisition of a 3D image dataset which is free of traces of a metal object imaged in the underlying 2D image datasets. A target function is defined into which data values of the 3D image dataset that are dependent on said substitute data values are incorporated following preprocessing. The substitute data values are then varied iteratively until the value of the target function satisfies a predetermined criterion. Residual artifacts that still persist following the interpolation can thus be effectively reduced.

Abstract: A method is provided for supplying a 3D X-ray image data record for a moving object. The said object contains highly X-ray radiation-absorbent material. A correction is made in respect of the highly absorbent material in 2D forward projections obtained from a 3D-X-ray image data record. The forward projections are calculated using 3D motion fields, which are derived from original 2D X-ray image data records.

Abstract: A method for reconstruction of a three-dimensional image data set from projection images of an object captured with an X-ray device from different projection angles is proposed. At least one sub-area of the object is outside the coverage of the X-ray device, or as a result of strong attenuation by a metal so that no projection data is present in the sub-area. Filter lines are determined n the projection images. A first local transformation is performed along the filter lines on the projection images. The missing projection data on the transformed projection data is augmented. A non-local transformation is performed on the transformed projection data for determining of filtered, augmented projection data. The non-local transformation is different from a ramp filter which is created by the first local transformation and the non-local transformation. The three-dimensional image data set is determined by back-projection of the filtered, augmented projection data.

Abstract: The invention relates to a method and a device for increasing contrast in medical images generated by an imaging system featuring an x-ray source and a detector. The detector detects x-rays of the x-ray source and converts image signals from the x-rays. The image signals are transferred to a control and processing unit for processing. Deconvolution of the image signals is carried out by application of an inverse modulation transfer function modified by a regularization. At least a volume image can be reconstructed from the deconvolved image signals.

Abstract: In a computer tomography method an object region of the object being examined is determined in that projection beams that are linked with maximum attenuation are sought in cropped projection images. A central point of the object region is then determined and the object sections associated with the projection beams plotted on the central point. The object region can be at least approximately determined using the end points of the object sections.

Abstract: A method for creating material-selective volume images of various material components of an object to be examined is proposed. The method is based on multi-spectral projected images captured from various directions of projection, the images being captured using an X-ray machine, and makes it possible to quantitively exactly determine the material-selective volume images by way of iteration.

Abstract: A provisional three-dimensional reconstruction of an examination object is determined based on two-dimensional original projection images. Provisional metal volumes are determined on the reconstruction by segmentation and mapped into the original projection images to define provisional metal areas. Edge points on edge zones of the provisional metal areas are selected. Data values of the original projection images within the provisional metal areas are modified as a function of data values of the selected edge points to determine modified projection images. Differential images are determined based on the original projection images and the corresponding modified projection images. Definitive metal areas are determined in the differential images by segmentation. The differential images are added to the modified projection images with the definitive metal areas deducted.
