Abstract: The disclosure describes one or more embodiments of systems, methods, and non-transitory computer-readable media that modify vertex positions of a 3D-object mesh to align the vertices with discontinuities indicated by a sharpness map for a displacement map. For example, the disclosed systems access a sharpness map that encodes discontinuities of a displacement map to preserve sharp features. During sharp tessellation, for a given vertex of the 3D-object mesh, the disclosed systems iterate over neighboring vertices to search for a nearest intersection between one of the incident edges of the vertex and neighboring vertices and a discontinuity line from the sharpness map. Then, the vertex is moved within a threshold distance of the nearest discontinuity line intersection along the incident edge. The disclosed systems similarly reposition other vertices of the 3D-object mesh to generate a modified 3D-object mesh that includes vertices that align with discontinuities present in a displacement map.

Abstract: An antenna arrangement includes a conductive element configured to resonate at and above a chosen electromagnetic radiation frequency corresponding to a fundamental resonant mode. The conductive element is folded to make coupling areas intended to shift one or more of the resonant frequencies of the higher resonant modes. Each coupling area is defined related to the set of resonant frequencies according to which the antenna is supposed to work, and is formed by positioning parts of the conductive element facing each other. The location, along the conductive element, of the parts of that conductive element intended to form a given coupling area as well as the length of these parts and as the width of the gap between them when the coupling area is formed, are determined so as to provide a given increase or decrease of the resonant frequency of a given resonant mode of the conductive element.

Abstract: The disclosure describes one or more embodiments of systems, methods, and non-transitory computer-readable media that utilize a sharpness map that includes information on how to filter a displacement map on a per-texel basis to preserve sharp features while sampling a displacement map. For instance, the disclosed systems utilize a sharpness map that encodes combinable patterns to represent discontinuities of features within a displacement map. In some embodiments, the disclosed systems generate a sharpness map having texels encoded with discontinuity configurations that are referenced to control filtering (e.g., via interpolation) of a displacement map such that sharp features within the displacement map are not lost (due to smoothing during interpolation). For example, the disclosed systems filter feature values of a displacement map using discontinuities identified within a sharpness map to interpolate when the feature value(s) and a sampling point are identified as being on the same side of a discontinuity.

Abstract: A decoder for determining an estimate of a vector of information symbols carried by a signal received through a transmission channel represented by a channel matrix is provided. The decoder includes a block division unit configured to divide the vector of information symbols into two or more sub-vectors, each sub-vector being associated with a block level; two or more processors configured to determine, in parallel, candidate sub-vectors and to store the candidate sub-vectors in a first stack. Each processor is configured to determine at least a candidate sub-vector by applying a symbol estimation algorithm and to store each candidate sub-vector with a decoding metric and the block level associated with the candidate sub-vector. The decoding metric is lower than or equal to a decoding metric threshold. A processor among the two or more processors is configured to determine at least a candidate vector from candidate sub-vectors stored in the first stack, the candidate vector being associated with a cumulated decoding metric and to update the decoding metric threshold from the cumulated decoding metric.

Abstract: A method for generating a reduced-blur digital image representing a scene, the method being computer-implemented and comprising the following successive steps: i) providing at least two digital source images, a same element of the scene being represented in at least two source images, ii) selecting a reference image among the source images, iii) for at least one source image different from the reference image, and for at least one pixel of the reference image, a) defining a pattern in the reference image comprising pixels of the reference image, the element being represented in said pattern, b) constructing a map of coordinates that associates coordinates of the pattern in the reference image with the coordinates of the most similar pattern in the source image, c) optionally, filtering of the map of coordinates, and d) generating a corrected image by assigning to a pixel of the corrected image, the position of the pixel of the reference image and a color extracted from the source image point which position is defined by the, optionally filtered, map of coordinates, iv) generating the reduced-blur image by processing, with a multifocus image fusion technique, the corrected image(s) and the reference image.

Abstract: A method and device to modulate an FBMC/OQAM signal, the device comprising at least one QAM mapper mapping a binary stream into complex symbols, a first and a second transmission chain. Each chain comprises: a precoder transposing respective sets of symbols into frequency domain real/imaginary samples, a phase rotator applying a phase quadrature keying to said samples, an FBMC modulator to modulate the output of the phase rotator into an FBMC symbol. The device further comprises an adder of the output of the first transmission chain with a delayed output of the second transmission chain, and is configured to insert guard interval sequences into the binary stream or into the symbols processed by the precoders. A corresponding radio communication equipment, computer program and readable medium is provided.

Abstract: A mechanism for attributing users to a plurality of sub bands in a time slot t in a multiple access communications system, said method comprising assigning a combination of users to a sub band on a Proportional Fairness basis, that is to say whichever combination of users maximizes a Proportional Fairness performance metric for that channel, where the performance metric is weighted by a weighting factor reflecting the difference for that user between a target throughput and a projected throughput.

Abstract: A reflecting cell including at least two substrates each covered by an electrode and facing each other, the substrates delimitating between them a volume which separates them and which is filled with a bistable liquid crystal-type material with a threshold field, for example a cholesteric liquid crystal, both electrodes being intended to be connected to a voltage source. This cell is characterized in that at least one of the electrodes is formed by associating a pattern, which does not entirely cover the surface of the substrate considered, and a conducting layer which covers the surface of the substrate considered, the conductivity of the material of the layer being lower than that of the material of the pattern.
