Abstract: Aspects of the present disclosure relate to systems and methods for active depth sensing. An example apparatus configured to perform active depth sensing includes a projector. The projector is configured to emit a first distribution of light during a first time and emit a second distribution of light different from the first distribution of light during a second time. A set of final depth values of one or more objects in a scene is based on one or more reflections of the first distribution of light and one or more reflections of the second distribution of light. The projector may include a laser array, and the apparatus may be configured to switch between a first plurality of lasers of the laser array to emit light during the first time and a second plurality of laser to emit light during the second time.

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: 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.
