A method includes generating image signals from which a two-dimensional image is generated. The method includes generating object image signals by capturing an examination object arranged in a space. The method includes generating overview image signals by capturing an overview of the space. The method includes receiving image information included in the generated object image signals and the generated overview image signals. The method includes combining a two-dimensional object image, generated from the object image signals, with a two-dimensional perspectively distorted overview image of the space, generated from the overview image signals, to form a two-dimensional output image. The method includes scaling the received image information with respect to an image size for forming the output image in a manner such that at least one dimension of the examination object captured both in the object image and in the overview image has a same size in the output image.

A method for training a neural network includes receiving a plurality of images and, for each individual image of the plurality of images, generating a training triplet including a subset of the individual image, a subset of a transformed image, and a homography based on the subset of the individual image and the subset of the transformed image. The method also includes, for each individual image, generating, by the neural network, an estimated homography based on the subset of the individual image and the subset of the transformed image, comparing the estimated homography to the homography, and modifying the neural network based on the comparison.

Methods and systems disclosed herein relate generally to systems and methods for transforming document elements in response to modifications to a layout of a document. A layout-modification application identifies, from a first document having a first document layout, a first set of measurements of a document element and a first location of the document element within the first document. Based on an aspect-ratio difference between the first document layout and a second document layout, the layout-modification application selects a set of transformation rules that specify, for the document element, a second set of measurements and a second location within a second document. To select the particular set of transformation rules, the layout-modification application uses the determined aspect-ratio difference. The layout-modification application applies the selected set of transformation rules to the document element.

The present application provides a method of processing video data. The method of processing video data includes obtaining a frame of video including M numbers of first pixel groups along a first direction, each of the M numbers of first pixel groups including N numbers of pixels along a second direction, M and N being positive integers; determining Q numbers of first pixel sets for each respective one of the M numbers of first pixel groups; assigning Q numbers of pixels values respectively to the Q numbers of first pixel sets for each respective one of the M numbers of first pixel groups; generating M numbers of second pixel groups respectively for the M numbers of first pixel groups; and obtaining a processed frame of video including the M numbers of second pixel groups along the first direction.

Systems and methods are provided for performing temporally consistent depth map generation by implementing acts of obtaining a first stereo pair of images of a scene associated with a first timepoint and a first pose, generating a first depth map of the scene based on the first stereo pair of images, obtaining a second stereo pair of images of the scene associated with at a second timepoint and a second pose, generating a reprojected first depth map by reprojecting the first depth map to align the first depth map with the second stereo pair of images, and generating a second depth map that corresponds to the second stereo pair of images using the reprojected first depth map.

In accordance with a method for dose estimation for the irradiation of an object, a model with a total number of spatial elements is provided on a memory element. For each spatial element, the model specifies a material composition of the object. A neighborhood material composition is determined for a neighborhood of spatial elements depending on the model by a computing unit. A radiation dose for the neighborhood with regard to an ionizing radiation is determined with aid of a simulation depending on the neighborhood material composition. A dose distribution for the object with regard to the ionizing radiation is determined based on the radiation dose for the neighborhood.

An apparatus and method are described for a non-uniform rasterizer. For example, one embodiment of an apparatus comprises: a graphics processor to process graphics data and render images using the graphics data; and a non-uniform rasterizer within the graphics processor to determine different resolutions to be used for different regions of an image, the non-uniform rasterizer to receive a plurality of polygons to be rasterized and to responsively rasterize the polygons in accordance with the different resolutions.

The present invention provides an apparatus comprising a plurality of image sensors, an image frame multiplexer communicable with each of the plurality of image sensors, and a processor communicable with the image frame multiplexer. Each image sensor captures a full frame image data object and outputs a middle frame image data object. The image frame multiplexer communicable receives a plurality of middle frame image data objects and outputs a selected middle frame image data object from the plurality of middle frame image data objects. The processor receives the selected middle frame image data object and processes the selected middle frame image data object.

A demosaicing method applied to an image having pixels each corresponding to an initial spectral band, to obtain a demosaiced image with several spectral bands having pixels each corresponding to the initial spectral band or to an interpolated spectral band. The method includes: on the basis of reference patches and for each reference patch: a determination of a set of patches similar to the reference patch, a determination of a covariance matrix for |the set of patches, and for each patch, a calculation of estimates of the interpolated spectral bands according to a block-based deconstruction of the covariance matrix, where the deconstruction into four blocks is according to phasing of each patch, and a determination of the interpolated spectral bands by an aggregation of estimates of the interpolated spectral bands, where the estimates of the interpolated spectral bands are aggregated for each pixel.
