摘要： The present application discloses an image processing method for deriving an edge-guided motion vector of a first pixel of a current frame. The image processing method includes: calculating similarity metrics of the first pixel according to a reference frame, wherein the similarity metrics are associated with candidate motion vectors of the first pixel, respectively; obtaining a reference motion vector of a reference pixel of the current frame; calculating penalties caused by the reference pixel according to an edge strength of the reference pixel and an edge strength of the first pixel, wherein the greater the edge strength of the reference pixel, the greater the penalties; and selecting the edge-guided motion vector from the candidate motion vectors according to the similarity metrics, the candidate motion vectors, and the penalties.

摘要： A method for representing a three-dimensional scene stored as a three-dimensional data set includes determining a set of P depth-plane depths along a viewing direction. The method includes generating, from a three-dimensional data set, a proxy three-dimensional data set including Pproxy images by, for each depth-plane depth: generating a proxy image of the Pproxy images from at least one cross-sectional image of a plurality of transverse cross-sectional images that (i) constitute the three-dimensional data set and (ii) each represent a respective transverse cross-section of the three-dimensional scene at a respective scene-depth.

摘要： A cross reality system that provides an immersive user experience by storing persistent spatial information about the physical world that one or multiple user devices can access to determine position within the physical world and that applications can access to specify the position of virtual objects within the physical world. Persistent spatial information enables users to have a shared virtual, as well as physical, experience when interacting with the cross reality system. Further, persistent spatial information may be used in maps of the physical world, enabling one or multiple devices to access and localize into previously stored maps, reducing the need to map a physical space before using the cross reality system in it. Persistent spatial information may be stored as persistent coordinate frames, which may include a transformation relative to a reference orientation and information derived from images in a location corresponding to the persistent coordinate frame.

摘要： An electronic device may include scaling circuitry to scale input pixel data to a greater resolution. The directional scaling circuitry may include first interpolation circuitry to receive best mode data, including one or more angles corresponding to content of the image and interpolate first pixel values at first pixel positions diagonally offset from input pixel positions of the input pixel data based on the best mode data and input pixel values corresponding to the input pixel positions. The directional scaling circuitry may also include second interpolation circuitry to receive the best mode data and the input pixel values and interpolate second pixel values at second pixel positions horizontally or vertically offset from the input pixel positions based at least in part on the best mode data and the input pixel values.

摘要： A substrate processing apparatus that includes a substrate holder, a cup member, an elevating mechanism, a first nozzle, and a camera. The substrate holder holds a substrate and rotates the substrate. The cup member surrounds the outer circumference of the substrate holder. The elevating mechanism moves up the cup member so that the upper end portion of the cup member is located at the upper end position higher than the substrate held by the substrate holder. The first nozzle has a discharge port at a position lower than the upper end position, and discharges first processing liquid from the discharge port to an end portion of the substrate. The camera images an imaging region that includes the first processing liquid discharged from the discharge port of the first nozzle and is viewed from an imaging position above the substrate.
