摘要： Methods and apparatuses for data pruning for video compression using example-based super resolution are provided. A method and apparatus for encoding is provided in which patches of video are extracted from input video, grouped together using a clustering method, and representative patches are packed into patch frames. The original video is downsized and sent either along with, or in addition to, the patch frames. At a decoder, the method and apparatus provided extract patches from the patch frames and create a patch library. The regular video frames are upsized and the low resolution patches are replaced by patches from the patch library by searching the library using the patches in the decoded regular frames as keywords. If there are no appropriate patches, no replacement is made. A post processing procedure is used to enhance the spatiotemporal smoothness of the recovered video.

摘要： A system and method for extracting depth information from at least two images employing region-based filtering for reducing artifacts are provided. The present disclosure provides a post-processing algorithm or function for reducing the artifacts generated by scanline Dynamic Programming (DP) or other similar methods. The system and method provides for acquiring a first image and a second image from a scene, estimating the disparity of at least one point in the first image with at least one corresponding point in the second image to generate a disparity map, segmenting at least one of the first or second images into at least one region, and filtering the disparity map based on the segmented regions. Furthermore, anisotropic filters are employed, which have a great smoothing effect along the vertical direction than that of the horizontal direction, and therefore, reduce stripe artifacts without significantly blurring the depth boundaries.

摘要： Methods and Systems are provided for converting a two-dimensional image sequence into a three-dimensional image. In one embodiment, a method for converting a two-dimensional image sequence into a three-dimensional image includes determining camera motion parameters between consecutive images in a monoscopic sequence of reference 2D images, wherein the consecutive images comprise a current reference image and an adjacent image, determining a horizontal disparity map for a target image using the camera motion parameters, determining a disparity probability value for each disparity vector of the disparity map, and determining a target image as a weighted average of pixel values in the current reference image using the disparity probability values, such that the target image and current reference image comprise a stereoscopic image pair.

摘要： A system and method for compositing 3D images that combines parts of or at least a portion of two or more images having 3D properties to create a 3D image. The system and method of the present disclosure provides for acquiring at least two three-dimensional (3D) images, obtaining metadata (e.g., lighting, geometry, and object information) relating to the at least two 3D images, mapping the metadata of the at least two 3D images into a single 3D coordinate system, and compositing a portion of each of the at least two 3D images into a single 3D image. The single 3D image can be rendered into a desired format (e.g., stereo image pair). The system and method can associate the rendered output with relevant metadata (e.g., interocular distance for stereo image pairs).
