Abstract: 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.

Abstract: An apparatus, system, and method for increasing points in a point cloud. In one illustrative embodiment, a two-dimensional image of a scene and the point cloud of the scene are received. At least a portion of the points in the point cloud are mapped to the two-dimensional image to form transformed points. A fused data array is created using the two-dimensional image and the transformed points. New points for the point cloud are identified using the fused data array. The new points are added to the point cloud to form a new point cloud.

Abstract: To obtain a three-dimensional virtual reconstruction of a workpiece the workpiece is positioned on a display screen between the display screen and at least one imager wherein the imager acquires multiple images of the workpiece while (a) multiple light stripes are displayed and swept in a first directional orientation across the display screen, (b) multiple light stripes are displayed and swept in at least one second directional orientation across the display screen, and (c) multiple images for each position of the multiple light stripes at different exposure times are captured. From the multiple images, a difference caused by the workpiece in a width and a profile of the multiple light stripes is determined. That difference is used to calculate a depth value (z) of the workpiece at each imager pixel position (x, y). The calculated depth value is used to reconstruct a surface shape of the workpiece.

Abstract: A device may include a video coder to determine an equivalent quantization parameter (QP) for a decoded block of video data using a quantization matrix for the decoded block of video data, determine deblocking parameters based on the determined equivalent QP, and deblock an edge of the decoded block based on the determined deblocking parameters. In particular, the video coder may determine equivalent QPs for two neighboring blocks defining a common edge, and deblock the common edge based on the equivalent QPs. The video coder may determine deblocking parameters, such as ? and tc values, based on the equivalent QPs. The video coder may then deblock the common edge based on the deblocking parameters, e.g., determine whether to deblock the common edge, determine whether to apply a strong or a weak filter to the common edge, and determine a width (in number of pixels) for a weak filter.

Abstract: Multi-view autostereoscopic displays provide an immersive, glasses-free 3D viewing experience, but they preferably use correctly filtered content from multiple viewpoints. The filtered content, however, may not be easily obtained with current stereoscopic production pipelines. The proposed method and system takes a stereoscopic video as an input and converts it to multi-view and filtered video streams that may be used to drive multi-view autostereoscopic displays. The method combines a phase-based video magnification and an interperspective antialiasing into a single filtering process. The whole algorithm is simple and may be efficiently implemented on current GPUs to yield real-time performance. Furthermore, the ability to retarget disparity is naturally supported. The method is robust and works transparent materials, and specularities. The method provides superior results when compared to the state-of-the-art depth-based rendering methods.

Abstract: An apparatus and method for selecting the use of inter-prediction or intra-prediction during enhanced encoding and decoding of Bayer images. Intra-plane predictions rely on correlation between neighboring pixels of the same color, while inter-plane predictions rely on correlation between neighboring pixels in different color planes (i.e., different colors). A dynamic range decision is made to select whether to use the intra-plane or inter-plane prediction, towards eliminating large residuals which can arise in certain large edge situations.

Abstract: Synchronizing cameras, connected via a telecommunication network, for capturing a multi-view session can be controlled by a synchronization module. The synchronization module determines a multi-view capturing parameter from a capturing parameter that is received from at least one camera. The multi-view capturing parameter is provided by the synchronization module to the cameras participating in the capturing session in order to synchronize the capturing of the multi-view session. Further, a camera device informs the synchronization module of the disposability and capturing parameter of the camera. The camera receives the multi-view capturing parameter for use in capturing the session.
