摘要： Several implementations relate to 3D video formats. One or more implementations provide adaptations to MVC and SVC to allow 3D video formats to be used. According to a general aspect, a set of images including video and depth is encoded. The set of images is related according to a particular 3D video format, and are encoded in a manner that exploits redundancy between the set of images. The encoded images are arranged in a bitstream in a particular order, based on the particular 3D video format that relates to the images. The particular order is indicated in the bitstream using signaling information. According to another general aspect, a bitstream is accessed that includes the encoded set of images. The signaling information is also accessed. The set of images is decoded using the signaling information.

摘要： Systems and methods for encoding/decoding a 3D image are provided. The system decomposes depth map into a plurality of component depth maps (CDMs) for a plurality of depth ranges, wherein each component depth map corresponds to a focal plane of a multiple focal plane (MFP) decomposition of the image data. The system generates a plurality of component depth map focal planes (CDMFPs) by combining each respective CDM with the depth map. The system scales data in each CDMFP by a respective scaling factor. The system generates for transmission a plurality of encoded scaled CDMFP data streams for the plurality of depth ranges, wherein each respective scaled CDMFP data stream is based at least in part on a respective scaled CDMFP.

摘要： A method for calibrating at least one of the six-degrees-of-freedom of all or part of cameras in a formation positioned for scene capturing, the method comprising a step of initial calibration before the scene capturing. The step comprises creating a reference video frame which comprises a reference image of a stationary reference object. During scene capturing the method further comprises a step of further calibration wherein the position of the reference image of the stationary reference object within a captured scene video frame is compared to the position of the reference image of the stationary reference object within the reference video frame, and a step adapting the at least one of the six-degrees-of-freedom of a multiple cameras of the formation if needed in order to get an improved scene capturing after the further calibration.

摘要： This disclosure is directed to coding a multi-view signal, which includes processing a list of plurality of motion vector candidates associated with a coding block of a current picture in a dependent view of the multi-view signal Such processing includes estimating a first motion vector based on a second motion vector associated with a reference block in a current picture of a reference view of the multi-view signal, the reference block corresponding to the coding block of the current picture in the dependent view. The first motion vector is added into the list, and an index is used that specifies at least one candidate from the list to be used for motion-compensated prediction. The coding block in the current picture is coded by performing the motion-compensated prediction based on the at least one candidate indicated by the index.

摘要： A stereo image generation method and an electronic apparatus using the same are provided. The stereo image generation method includes the following steps. A two-dimensional (2D) original image corresponding to a first viewing angle is obtained, and a depth map of the 2D original image is estimated. Interpupillary distance information of a user is detected. A pixel shift processing is performed on the 2D original image according to the interpupillary distance information and the depth map to generate a reference image corresponding to a second viewing angle. An image inpainting processing is performed on the reference image to obtain a restored image. The restored image and the 2D original image are merged to generate a stereo image conforming to a stereo image format.

摘要： An image sensor suitable for use in an augmented reality system to provide low latency image analysis with low power consumption. The image sensor may have multiple pixel cells, each of the pixel cells comprising a photodetector to generate an electric signal based on an intensity of light incident upon the photodetector. The pixel cells may include multiple subsets of pixel cells, each subset of pixel cells including at least one angle-of-arrival to-intensity converter to modulate incident light reaching one or more of the pixel cells in the subset based on an angle of arrival of the incident light. Each pixel cell within the plurality of pixel cells may include differential readout circuitry configured to output a readout signal only when an amplitude of a current electric signal from the photodetector is different from an amplitude of a previous electric signal from the photodetector.

摘要： An optical inspection system is provided for an ultraviolet laser and associated optics forming a planar laser sheet directed to a glass sheet. The planar laser sheet intersects a surface of the glass sheet thereby causing the surface of the glass sheet to fluoresce and form a visible wavelength line on the surface. A camera has an image sensor for detecting the visible wavelength line. A control system in configured to receive image data indicative of the visible wavelength line, analyze and triangulate the data to determine a series of coordinates associated with the line, and create a three-dimensional map of the surface of the glass sheet as a function of the series of coordinates. Methods for using an optical inspection system, for gauging a surface using an optical inspection system, and for providing optical reflectance information for a surface using an optical inspection system are also provided.
