A gateway device between a first and second communication network outside the gateway device handles communication between a first device in the first network and a second device in the second network. When the gateway receives a communication request from the first device, directed to the second device, for performing a first cryptographic data communication protocol, the gateway determines whether the first cryptographic data communication protocol is registered as unsafe in the gateway device, and/or registered as safe, in particular whether it is safe against key reconstruction by a quantum computer. When the first cryptographic data communication protocol is not registered as unsafe in the gateway device, and/or registered as safe, the gateway device forwards messages exchanged as part of execution of the first cryptographic data communication protocol between the first and second device. When the gateway determines that the first cryptographic data communication protocol is registered as unsafe in the gateway device, and/or not registered as safe, the gateway device executes the first cryptographic data communication protocol between the first device and the gateway device, and executes a second cryptographic data communication protocol, which is not recorded as unsafe in the gateway device, and/or registered as safe, between the gateway and the second device, whereby the first and second cryptographic data communication protocol are executed sequentially to communicate data between the first and second device via the gateway device. |

Method and arrangement for predicting switching times of a signal group of a signal installation for controlling a flow of traffic
Real state information, which influences the switching times of a light signal system, is supplied as input signals to a first neural network in a fixed time cycle.

This estimated state information is output to artificial intelligence which predicts the switching times. The first neural network allows the artificial intelligence to also make good predictions for the switching times of signal groups when one of the many communication paths involved fails or is overloaded. It is therefore possible to predict signal group states in the fixed time cycle in real time with a high degree of robustness and tolerance with respect to gaps in the time cycle of the real state information provided. |

Facial synthesis in augmented reality content for online communities
The subject technology captures first image data by a computing device, the first image data comprising a target face of a target actor and facial expressions of the target actor, the facial expressions including lip movements. The subject technology generates, based at least in part on frames of a source media content, sets of source pose parameters. The subject technology receives a selection of a particular facial expression from a set of facial expressions. The subject technology generates, based at least in part on sets of source pose parameters and the selection of the particular facial expression, an output media content. The subject technology provides augmented reality content based at least in part on the output media content for display on the computing device. |

Method for determining one or more storage boxes for storing objects
The present disclosure relates to a computer implemented method for determining one or more storage boxes for storing objects. The method comprising: scanning, by an imaging sensor, a plurality of objects to be stored thereby acquiring a scan of the plurality of objects; segmenting the scan of the plurality of objects into objects; determining a three-dimensional, 3D, measure of each of the segmented objects; grouping the segmented objects into one or more groups of objects; determining, for a group of objects, one or more candidate storage boxes for storing the objects of the group of objects by calculating a total 3D measure for the objects of the group of objects by combining the 3D measure of each of the objects of the group of objects and comparing the total 3D measure for the objects of the group of objects with inner dimensions of a set of potential storage boxes. |

Scalable road sign interpretation system for autonomous driving
A road sign interpretation system includes a front-facing camera mounted on or in a vehicle collecting image data of multiple road signs. A first convolutional neural network (CNN) receives the image data from the front-facing camera and yields a set of sign predictions including one or more sign text instances. A second CNN defining a text extractor receives the image data from the front-facing camera and extracts text candidates including the multiple sign text instances. Sign and sign data localization is provided in the second CNN to compute a text order from the multiple sign text instances. A sign text synthesizer module receives individual sign text instances from the first CNN and individual ones of the sign text instances in digitized forms from an optical character recognizer (OCR). A semantic encoding and interpretation module receives the sign text instances and identifies semantics of the multiple road signs. |

Station monitoring apparatus, station monitoring method, and non-transitory computer readable medium
A station monitoring apparatus (10) includes an image processing unit (110) and a decision unit (120). The image processing unit (110) determines a position of a door (50) of a vehicle (40) and a position of a person by analyzing an image generated by a capture apparatus (20), i.e., an image capturing a platform of a station. The decision unit (120) decides, after the vehicle (40) has begun to move, by use of a position of the door (50) and a position of the person, whether to perform predetermined processing. For example, the decision unit (120) performs the predetermined processing when deciding that a difference between a movement velocity of any of the persons and a movement velocity of the door is within a criterion continuously for a criterion time. |

Repeatability predictions of interest points
The present disclosure describes approaches for evaluating interest points for localization uses based on a repeatability of the detection of the interest point in images capturing a scene that includes the interest point. The repeatability of interest points is determined by using a trained repeatability model. The repeatability model is trained by analyzing a time series of images of a scene and determining repeatability functions for each interest point in the scene. The repeatability function is determined by identifying which images in the time series of images allowed for the detection of the interest point by an interest point detection model. |
