  • Method for enhancing depth images of scenes using trellis structures
    Patent number: 8994722
    Abstract: An image for a virtual view of a scene is generated based on a set of texture images and a corresponding set of depth images acquired of the scene. A set of candidate depths associated with each pixel of a selected image is determined. For each candidate depth, a cost that estimates a synthesis quality of the virtual image is determined. The candidate depth with a least cost is selected to produce an optimal depth for the pixel. Then, the virtual image is synthesized based on the optimal depth of each pixel and the texture images. The method also applies first and second depth enhancement before, and during view synthesis to correct errors or suppress noise due to the estimation or acquisition of the dense depth images and sparse depth features.

  • Joint depth estimation
    Patent number: 8913105
    Abstract: Various implementations are described. Several implementations relate to joint depth estimation for multiple depth maps. In one implementation, a first-view depth indicator for a location in a first view is estimated, and a second-view depth indicator for a corresponding location in a second view is estimated. The estimating of one or more of the first-view depth indicator and the second-view depth indicator is based on a constraint. The constraint provides a relationship between the first-view depth indicator and the second-view depth indicator for corresponding locations.

  • Disparity estimation for misaligned stereo image pairs
    Patent number: 8867826
    Abstract: A disparity vector for a pixel in a right image corresponding to a pixel in a left image in a pair of stereo images is determined. The disparity vector is based on a horizontal disparity and a vertical disparity and the pair of stereo images is unrectified. First, a set of candidate horizontal disparities is determined. For each candidate horizontal disparity, a cost associated with a particular horizontal disparity and corresponding vertical disparities is determined. The vertical disparity associated with a first optimal cost is assigned to each candidate horizontal disparity, so that the candidate horizontal disparity and the vertical disparity yield a candidate disparity vector. Lastly, the candidate disparity vector with a second optimal cost is selected as the disparity vector of the pixel in the right image.

    Publication number: 20140301479
    Abstract: Implementations are provided that relate, for example, to view tiling in video encoding and decoding. A particular method includes accessing a video picture that includes multiple pictures combined into a single picture (826), accessing information indicating how the multiple pictures in the accessed video picture are combined (806, 808, 822), decoding the video picture to provide a decoded representation of at least one of the multiple pictures (824, 826), and providing the accessed information and the decoded video picture as output (824, 826). Some other implementations format or process the information that indicates how multiple pictures included in a single video picture are combined into the single video picture, and format or process an encoded representation of the combined multiple pictures.

  • Method and system for processing multiview videos for view synthesis using motion vector predictor list
    Patent number: 8823821
    Abstract: Multiview videos are acquired by overlapping cameras. Side information is used to synthesize multiview videos. A reference picture list is maintained for current frames of the multiview videos, the reference picture indexes temporal reference pictures and spatial reference pictures of the acquired multiview videos and the synthesized reference pictures of the synthesized multiview video. Each current frame of the multiview videos is predicted according to reference pictures indexed by the associated reference picture list with a skip mode and a direct mode, whereby the side information is inferred from the synthesized reference picture. In addition, the skip and merge modes for single view video coding are modified to support multiview video coding by generating a motion vector prediction list by also considering neighboring blocks that are associated with synthesized reference pictures.

  • DEPTH CODING
    Publication number: 20140184744
    Abstract: Various implementations address depth coding and related disciplines. In one particular implementation, a segmentation is determined for a particular portion of a video image in a sequence of video images. The segmentation is determined based on reference depth indicators that are associated with at least a portion of one video image in the sequence of video images. Target depth indicators associated with the particular portion of the video image are processed. The processing is based on the determined segmentation in the particular portion of the video image. In another particular implementation, a segmentation is determined for at least a given portion of a video image based on depth indicators associated with the given portion. The segmentation is extended from the given portion into a target portion of the video image based on pixel values in the given portion and on pixel values in the target portion.

  • Process for preparing high molecular weight polyesters
    Patent number: 8748562
    Abstract: A process for producing higher molecular weight polyester includes heating a polyester to form a melt, and applying and maintaining a vacuum of between about 5 mm and about 85 mm of mercury to the melt while passing bubbles of gas through the melt until molecular weight has increased. The process may involve esterification of a diacid component and a diol component at elevated temperature. After the acid functional groups have essentially reacted, a vacuum of about 5 mm of mercury or less was applied and excess diol stripped off during transesterification, thereby increasing molecular weight.

    Abstract: A quality of a virtual image for a synthetic viewpoint in a 3D scene is determined. The 3D scene is acquired by texture images, and each texture image is associated with a depth image acquired by a camera arranged at a real viewpoint. A texture noise power is based on the acquired texture images and reconstructed texture images corresponding to a virtual texture image. A depth noise power is based on the depth images and reconstructed depth images corresponding to a virtual depth image. The quality of the virtual image is based on a combination of the texture noise power and the depth noise power, and the virtual image is rendered from the reconstructed texture images and the reconstructed depth images.
