A device for determining the surface topology and associated color of a structure, such as a teeth segment, includes a scanner for providing depth data for points along a two-dimensional array substantially orthogonal to the depth direction, and an image acquisition means for providing color data for each of the points of the array, while the spatial disposition of the device with respect to the structure is maintained substantially unchanged. A processor combines the color data and depth data for each point in the array, thereby providing a three-dimensional color virtual model of the surface of the structure. A corresponding method for determining the surface topology and associate color of a structure is also provided.

A method for acquiring a distance from a moving body to an object located in any direction of the moving body includes steps of: an image processing device (a) instructing a sweep network to project pixels of images, generated by cameras covering all directions of the moving body, onto main virtual geometries and apply 3D concatenation operation thereon to generate an initial 4D cost volume, (b) generating a final main 3D cost volume therefrom through a cost volume computation network, and (c) generating sub inverse distance indices corresponding to inverse values of sub separation distances between a sub reference point and sub virtual geometries, and main inverse distance indices corresponding to inverse values of main separation distances between a main reference point and the main virtual geometries, by using a sub cost volume and the final main 3D cost volume, to thereby acquire the distance to the object.

In some embodiments, a computer system displays a caption for a media item at different depths depending on the depth of the portion of the media item over which the caption is displayed. In some embodiments, a computer system displays a user interface element that includes information associated with the media item at different locations relative to the media item depending on attention of the user. In some embodiments, a computer system displays a user interface element that includes information associated with the media item with different visual appearances depending on visual characteristics of the portion of the media item over which the user interface element is displayed.

Techniques are provided for managing resources among clusters of computing devices in a computing system. Resource reassignment message are generated for indicating that servers are reassigned and in response to resource compute loads exceed or fall below certain thresholds. Techniques also include establishing communications with the reassigned servers to assign compute loads without physically relocating the servers from one cluster to another cluster.

A photo filter (e.g., artistic/stylized painting) light field effect system includes an eyewear device having a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. Execution of programming by a processor configures the stylized image painting effect system to apply a photo filter selection to: (i) a left raw image or a left processed image to create a left photo filter image, and (ii) a right raw image or a right processed image to create a right photo filter image. The stylized image painting effect system generates a photo filter stylized painting effect image with an appearance of a spatial rotation or movement, by blending together the left photo filter image and the right photo filter image based on a left image disparity map and a right image disparity map.

A system for single photon avalanche diode image capture is configurable to, over a frame capture time period, selectively activate an illuminator to alternately emit light from the illuminator and refrain from emitting light from the illuminator. The system is configurable to, over the frame capture time period, perform a plurality of sequential shutter operations to configure each SPAD pixel of the SPAD array to enable photon detection. The plurality of sequential shutter operations generates, for each SPAD pixel of the SPAD array, a plurality of binary counts indicating whether a photon was detected during each of the plurality of sequential shutter operations. The system is configurable to, based on a first set of binary counts of the plurality of binary counts, generate an ambient light image. The system is configurable to, based on a second set of binary counts of the plurality of binary counts, generate an illuminated image.
