Abstract: Methods and systems for enhancing elevation models with landcover feature data are provided. An example method involves accessing imagery covering an area of interest that contains an above-ground feature, generating, a digital surface model of the area of interest, extracting three-dimensional landcover feature data representing the above-ground feature that contains one or more actual ground-level points at the base of the above-ground feature, and generating a digital terrain model from the digital surface model at least in part by removing the above-ground feature from the digital surface model and filling at least some of the removed area with one or more of the actual ground-level points from the three-dimensional landcover feature data.

Abstract: A data processing system implements constructing a first prompt including a font mask of a reference character (RC) and a style prompt, sending the first prompt to a text2image model to iteratively generate salient content and concentrate the salient content within the font mask of RC as a first image of RC; concatenating two of the first images as a second image; generating a combined font mask of the font mask of RC and a font mask of a target character (TC); constructing a second prompt including the combined font mask and the second image, sending the second prompt to the model to iteratively generate salient content and in-paint the salient content within a half of the combined font mask as a third image of RC and TC; cropping a styled TC image from the third image using the font mask of TC; providing the styled TC image to a client device.

Abstract: A computer-implemented method includes receiving a real two-dimensional medical image of a patient, processing the real two-dimensional medical image with a computer-implemented generator configured to transfer the real two-dimensional medical image from a real image domain into a synthetic image domain, and analyzing the two-dimensional medical image transferred into the synthetic image domain with a machine-learning model. The machine-learning model was trained with a collection of synthetic two-dimensional medical images generated from real three-dimensional medical images.

Abstract: A display device includes: a display medium having a screen area in which pixels are disposed at regular intervals; and a controller that causes the display medium to display an image. The controller is configured to perform refresh process on target pixels that are included in a different pixel pattern for each predetermined refresh cycle. The target pixels being of the pixels disposed in the screen area and being distributed at intervals wider than the regular intervals.

Abstract: An apparatus includes first, second, and third units. The first unit is configured to obtain a first three-dimensional point based on an initial start point of a motion vector in one image of a stereo image and a point corresponding to the initial start point in the other image of the stereo image. The second unit is configured to obtain a second three-dimensional point based on an initial end point of the motion vector in the one image and a point corresponding to the initial end point in the other image. The third unit is configured to obtain, based on the first and second three-dimensional points, a third three-dimensional point for which a camerawork motion component has been removed from the second three-dimensional point and obtain, based on the third and first three-dimensional points, an amount of shake in the stereo image.

One of the systems includes a neural network configured to generate images, the neural network comprising a sequence of one or more first network blocks followed by a sequence of one or more second network blocks, wherein: each first network block is configured to perform operations comprising: applying a self-attention mechanism over at least a subset of first elements of a first block input to generate an updated first block input; and upsampling the updated first block input to generate a first block output; and each second network block is configured to perform operations comprising: processing a second block input using one or more neural network layers to generate an updated second block input; and upsampling the updated second block input to generate a second block output.

Abstract: An automated method for generating a prosthesis from a three dimensional (“3D”) scan data, the method includes generating an intermediate surface of the prosthesis extending toward an outside of a prepared tooth from a margin line of the prepared tooth in the 3D scan data, generating an inner surface of the prosthesis by determining a gap from a surface of the prepared tooth, generating an outer surface of the prosthesis and connecting the outer surface of the prosthesis and the intermediate surface of the prosthesis.

Abstract: A technique for performing ray tracing operations is provided. The technique includes detecting intersection of a ray with a split bounding volume of an instance of a bounding volume hierarchy; determining whether the split bounding volume meets an instance traversal limiting criterion; and continuing BVH traversal based on the determining.
