Abstract: Systems and techniques are provided for wireless communication. For example, a process can include obtaining a first image of an environment, the first image including a pattern of light. The process can further include determining a pixel window for a pixel of the first image; determining a set of transform pixels based on the pattern of light, wherein the set of transform pixels are a subset of pixels from the pixel window; performing a census transform based on the pixel and the set of transform pixels to obtain census transform information for the first image; and generating depth data based on the census transform information for the first image and census transform information for a second image.

Abstract: Systems and techniques are described for determining disparity information. For instance, a method for determining disparity information is provided. The method including: obtaining a plurality of cost functions; determining a first disparity for a center pixel of a first region of pixels at least in part by comparing one or more minima of a cost function of the center pixel to one or more minima of cost functions of other pixels in the first region; determining a second disparity for the center pixel at least in part by comparing one or more minima of a cost function of a center pixel of a second region to one or more minima of cost functions of other pixels in the second region, including the center pixel of the first region; and determining a third disparity for the center pixel of the first region based on the first disparity and the second disparity.

Abstract: An electronic imaging device and method for image capture are described. The imaging device includes a camera configured to obtain image information of a scene and that may be focused on a region of interest in the scene. The imaging device also includes a LIDAR unit configured to obtain depth information of at least a portion of the scene at specified scan locations of the scene. The imaging device is configured to detect an object in the scene and provides specified scan locations to the LIDAR unit. The camera is configured to capture an image with an adjusted focus based on depth information, obtained by the LIDAR unit, associated with the detected object.

Abstract: A method performed by an electronic device is described. The method includes obtaining a first image from a first camera, the first camera having a first focal length and a first field of view. The method also includes obtaining a second image from a second camera, the second camera having a second focal length and a second field of view disposed within the first field of view. The method further includes aligning at least a portion of the first image and at least a portion of the second image to produce aligned images. The method additionally includes fusing the aligned images based on a diffusion kernel to produce a fused image. The diffusion kernel indicates a threshold level over a gray level range. The method also includes outputting the fused image. The method may be performed for each of a plurality of frames of a video feed.

Abstract: Techniques and systems are provided for generating one or more depth maps. For example, a process can include transmitting a pattern of light using a structured light source, the pattern of light including at least a first sub-pattern group of a primitive pattern and a second sub-pattern group of the primitive pattern. The process can include generating an overlapped pattern of light, the overlapped pattern of light including at least the first sub-pattern group of the primitive pattern overlapped with the second sub-pattern group of the primitive pattern. The process can include receiving one or more return signals based on the overlapped pattern of light. The process can include generating a depth map based on the one or more return signals.

Abstract: A method and electronic device for selectively obtaining depth information at locations within a scene are described. Image content analysis is performed on a received image of the scene. Locations within the image to obtain depth information within the scene are determined based on the image analysis. The locations are provided to a LIDAR (light+radar) unit to selectively obtain depth information at the scene locations. The depth information is received from the LIDAR unit and a second image analysis is performed on a second image. The second image analysis is based on the image content of the second image and the received depth information. Updated locations based on the second image analysis may be provided to the LIDAR unit to obtain updated depth information.
