Abstract: By adding a side network to a face recognition network, output of early convolution blocks may be used to determine relative bounding box values. The relative bounding box values may be used to refine existing boundary box value with an eye on improving the generation, by the face recognition network, of embedding vectors.

Abstract: An exhaust line valve for an internal combustion engine. A closure body is arranged in a duct of the valve and is fastened to a shaft. The closure body when closed separates upstream and downstream duct sections. Two projections extend into the duct, each having a valve seat pointing in an opposite direction of the duct. By pivoting the closure body from its closed position, the sealing surfaces of the closure body are raised from their respective valve seats. A polymer seal is arranged on the valve seats and in the closed position the polymer seal sealingly contacts the associated sealing surface of the closure body. A circumferential surface of the shaft or the closure body is located in an edge region of the closure body. The polymer seal contacts in a sealing manner at least a region of the circumferential surface facing the upstream section of the duct.

Abstract: A valve for an exhaust gas line of an internal combustion engine in which a closure body is arranged in a duct and is positioned in a recess of a shaft, the closure body being pivotable about a rotation axis of the shaft. The closure body has two sides and a circumferential surface arranged between the two sides. The circumferential surface has sections with different external dimensions. A first external dimension of the circumferential surface of the closure body in a first section is smaller than the smallest internal dimension between end regions of the recess of the shaft in which the closure body sits. A second external dimension of the circumferential surface in a second section is greater than the smallest internal dimension of the recess of the shaft. The circumferential surface contacts the shaft in each of the two end regions of the recess.

Abstract: A safety valve for a compressed gas reservoir has an exhaust duct that is connected to the compressed gas reservoir, and a sealing element, which is arranged to move within the exhaust duct, and selectively opens the exhaust duct to the outside depending on an operating phase. The exhaust duct has a greater cross-sectional area on the side facing away from the compressed gas reservoir than on the side facing the compressed reservoir, and a constriction on the side of the sealing element facing away from the compressed reservoir.

Abstract: A system and method for accurately mapping between image coordinates and geo-coordinates, called geo-spatial registration. The system utilizes the imagery and terrain information contained in the geo-spatial database to precisely align geodetically calibrated reference imagery with an input image, e.g., dynamically generated video images, and thus achieve a high accuracy identification of locations within the scene. When a sensor, such as a video camera, images a scene contained in the geo-spatial database, the system recalls a reference image pertaining to the imaged scene. This reference image is aligned very accurately with the sensor's images using a parametric transformation. Thereafter, other information that is associated with the reference image can easily be overlaid upon or otherwise associated with the sensor imagery.

Abstract: The present invention is embodied in a method for representing and analyzing spatiotemporal data in order to make qualitative yet semantically meaningful distinctions among various regions of the data at an early processing stage. In one embodiment of the invention, successive frames of image data are analyzed to classify spatiotemporal regions as being stationary, exhibiting coherent motion, exhibiting incoherent motion, exhibiting scintillation and so lacking in structure as to not support further inference. The exemplary method includes filtering the image data in a spatiotemporal plane to identify regions that exhibit various spatiotemporal characteristics. The output data provided by these filters is then used to classify the data.

Abstract: Iris recognition is achieved by (1) iris acquisition that permits a user to self-position his or her eye into an imager's field of view without the need for any physical contact, (2) spatially locating the data defining that portion of a digitized video image of the user's eye that defines solely the iris thereof without any initial spatial condition of the iris being provided, and (3) pattern matching the spatially located data defining the iris of the user's eye with stored data defining a model iris by employing normalized spatial correlation for first comparing, at each of a plurality of spatial scales, each of distinctive spatial characteristics of the respective irises that are spatially registered with one another to quantitatively determine, at each of the plurality of spatial scales, a goodness value of match at that spatial scale, and then judging whether or not the pattern which manifests solely the iris of the user's eye matches the digital data which manifests solely the model iris in accordance
