Process for a vehicle control and information system

Abstract: A process for a vehicle control and information system in which data and traffic-related information are transmitted by means of at least one radio-transmission system between a vehicle and a central unit. A data-processing unit in the central unit and/or a data-processing unit in the vehicle are used to calculate at least one route, and the route data is transmitted by means of the data-transmission system between the vehicle and the central unit. The data-processing unit in the central unit and/or the data-processing unit in the vehicle simulate in real time the motion of the vehicle, the real-time simulation being carried out both in the vehicle-mounted data-processing unit and in the data-processing unit in the central unit using signals which are it transmitted over the radio transmission system. The vehicle position in the real-time simulation of the motion of the vehicle is displayed in the vehicle together with additional information relevant to the traffic.

Method for the transmission of digital signals

Abstract: A method for the transmission of digital signals, particularly in the AM bands (broadcasting bands), with high-level modulation, preferably 32 APSK or 64 APSK, being used for data blocks to be transmitted. At the receiving end, time-periodic measurements of a noise are carried out and noise signals determined therefrom are subtracted from received signals.

Semantic interoperability for the Web of Things

Abstract: This paper is co-authored by an informal group of experts from a broad range of backgrounds all of whom are active in standards groups, consortia and/or alliances in the Internet of Things (IoT) space. The ambition is to create mindshare on approaches to semantic interoperability and to actively encourage consensus building on what the co-authors regard as a key technical issue

Multiview Image Coding Using Depth Layers and an Optimized Bit Allocation

Abstract: In this paper, we present a novel wavelet-based compression algorithm for multiview images. This method uses a layer-based representation, where the 3-D scene is approximated by a set of depth planes with their associated constant disparities. The layers are extracted from a collection of images captured at multiple viewpoints and transformed using the 3-D discrete wavelet transform (DWT). The DWT consists of the 1-D disparity compensated DWT across the viewpoints and the 2-D shape-adaptive DWT across the spatial dimensions. Finally, the wavelet coefficients are quantized and entropy coded along with the layer contours. To improve the rate-distortion performance of the entire coding method, we develop a bit allocation strategy for the distribution of the available bit budget between encoding the layer contours and the wavelet coefficients. The achieved performance of our proposed scheme outperforms the state-of-the-art codecs for several data sets of varying complexity.
