Abstract: Systems and methods which obtain template images corresponding to pattern units of tessellated images using a template unit boundary identification technique are described. Template unit boundary identification techniques of embodiments operate to analyze a sample of a tessellated image to determine a template unit size for the template image, use the determined template unit size to define pixel analysis line segments for identifying template unit boundaries in the tessellated image, and select a template image based on the template unit boundaries identified using the pixel analysis line segments. One or more sample area images may be selected for use in determining a template unit size. Pixel analysis line segments, configured based upon a determined template unit size, may be used for identifying boundaries of a template unit. Moreover, dynamic template image updating may be provided.

Abstract: Systems and methods which provide iterative multi-directional image searching are described. Embodiments utilize a multi-directional searching pattern for defining one or more searching areas within a source image. A searching area of embodiments provides a searching area within a source image for searching for a template image in the multiple directions of the multi-directional searching pattern. A location of the searching area within the source image may be updated iteratively, such as based upon motion vectors derived from the searching, until a template image match position is identified within the source image. Embodiments transform the template image and the searching area within a source image to 1D representations corresponding to each direction of the multi-directional image search. Embodiments accommodate rotation and scale variance of the subject (e.g., object of interest) of the template image within the source image.

Abstract: Described is a method of reducing uplink inter-cell interference in a cellular communications network. The method comprises identifying in a cell any user equipments (UEs) which are susceptible to interference (ISUs) from another UE, particularly another UE in a neighboring cell. The method includes identifying in said cell any UEs causing interference (ICUs) to at least one neighboring cell and, more particularly, causing interference to a UE in a neighboring cell. The identified ISUs and ICUs are combined into a priority list for frequency resource reservation or allocation in said cell. The method may include limiting the identification of ISUs and ICUs to a selected number of UEs within the cell.

Abstract: Provided is a system for improving road safety of a vehicle. The system comprises a central management platform for managing a plurality of network cooperation engine (NCE) modules. Each NCE module manages a plurality of edge gateway devices (EGWs) which are each located in a respective defined geographical area of limited size. Each EGW communicates with multiple roadside units (RSUs) in its area and exchanges real-time and low latency information with said RSUs and with any vehicle on-board data processing units (ICGWs) in vehicles presently within its area. Each ICGW is adapted to be installable in a vehicle. The ICGW is configured to receive real-time data from one or more on-board vehicle modules. The ICGW is also configured to receive data from its EGW and the RSUs which are themselves configured to receive data from a plurality of sources located within said defined geographical area and to transmit said received data and/or data derived from said received data to said ICGW. The ICGW is configured to process data to autonomously determine any one or more of: a threat to the vehicle; an alert to be issued; and a control action to be implemented for the vehicle. A size of the defined geographical area may be selected such as to enable data from said EGW and/or RSUs to be transmitted to said ICGW in real-time or at least at or less than a first, low level of latency.

Abstract: Systems and methods which provide for accurate decoding of a received channel signal when station identifier information is unknown. Embodiments accurately decode a physical downlink control channel (PDCCH), such as to obtain downlink control information (DCI), without knowing radio network temporary identifier (RNTI) information. An unknown station identifier information (USII) of embodiments uses redundancy reduction-based error checking (performing error checking between data decoded from a candidate control channel data block containing redundant data and a portion of that candidate control channel data block containing redundancy reduced data) for implementing decoding when station identifier information is unknown. Embodiments of a USII decoder may use a power detection technique for identifying candidate control channel data blocks used in redundancy reduction-based error checking operation.

Abstract: A silicon carbide diode that contains a silicon carbide substrate, a silicon carbide layer on top of the silicon carbide substrate, two first lower barrier metal portions disposed on the silicon carbide layer and separated from each other along a top surface of the silicon carbide layer, and a first higher barrier metal portion connected to the two lower barrier metal portions. The silicon carbide layer is thinner and having lower doping than the silicon carbide substrate. The first higher barrier metal portion is located between the two first lower barrier metal portions on the silicon carbide layer along a direction of the top surface of the silicon carbide layer. By reducing the leakage current at the junction barrier, the reverse breakdown voltage of the silicon carbide diode is significantly improved.

Abstract: A method and a device for image inpainting on arbitrary surfaces in three-dimensional space are described for inpainting a region of a three-dimensional image utilizing a partial differential equation. The method includes obtaining a three-dimensional image on a surface S in three-dimensional space, and each point of the image includes an image point value and a position vector. The method includes locating an inpainting region D and generating an inpainting mask. The method further includes calculating image point values for points inside the inpainting region D and creating a second three-dimensional image to obtain an inpainted image. The present disclosure solves technical problems that previous methods do not work well on three-dimensional images on arbitrary surfaces and improves image inpainting technology.
