Patent number: 10757391Abstract: Techniques are disclosed for view generation based on a video coding scheme. A bitstream is received that is encoded based on the video coding scheme. The bitstream includes video, quantized warp map offsets, and a message of a message type specified by the video coding scheme. Depth samples decoded from the first bitstream are interpreted as quantized warp map offsets, based on a first syntax element contained in the message. Warp maps are generated based on the quantized warp map offsets and a second syntax element contained in the message. Views are generated using image-domain warping and based on the video and the warp maps.Type: GrantFiled: June 25, 2018Date of Patent: August 25, 2020Assignee: Disney Enterprises, Inc.Inventors: Aljosa Smolic, Nikolce Stefanoski

Patent number: 10740397Abstract: Disclosed is a system for linking transmedia content subsets. A memory stores a plurality of transmedia content data items and associated linking data, which define time-ordered content links between the transmedia content data items. The transmedia content data items are arranged into linked transmedia content subsets comprising different groups of the transmedia content data items and different content links therebetween; a transmedia content model that represents the transmedia content data items as nodes and the content links between the transmedia content data items as edges in one or more time-varying graphs. A processor is configured to associate the transmedia content data items with the time-ordered content links and store the linking data in the memory. It assigns the transmedia content data items to nodes of a graph structure, assign the time-ordered content links to edges of the graph structure, and store them in the transmedia content model.Type: GrantFiled: September 26, 2016Date of Patent: August 11, 2020Assignee: DISNEY ENTERPRISES, INC.Inventors: Aljosa Smolic, Miquel Angel Farre Guiu, Nikolce Stefanoski, Markus Gross, Adriano Galati

Patent number: 10257526Abstract: A video coding pipeline is provided that can accommodate high dynamic range (HDR) and wide color gamut (WCG) content at a fixed bitrate. The video coding pipeline relies on separate chromaticity and luminance-specific transforms in order to process image content. Image content may be converted into a nearly perceptually uniform color space for coding in constant luminance. Moreover, chromaticity transforms are utilized which reduce coding errors in the chroma components (at the fixed bitrate) by enlarging the distribution of code words for compression.Type: GrantFiled: September 22, 2015Date of Patent: April 9, 2019Assignee: Disney Enterprises, Inc.Inventors: Daniel Luginbuhl, Tunc Ozan Aydin, Aljosa Smolic, Nikolce Stefanoski

Patent number: 10121254Abstract: Methods and systems described herein detect object boundaries of videos. A window around the pixel may be followed in adjacent image frames of the image frame to determine object boundaries. Inconsistencies in image patches over a temporal window are detected, and each pixel of the image frame of a video is assigned an object boundary probability. The pixel may belong to a texture edge if the window content does not change throughout the adjacent image frames, or the pixel may belong to an object boundary if the window content changes. A probability value indicating the likelihood of the pixel belonging to an object boundary is determined based on the window content change and is assigned to the corresponding pixel.Type: GrantFiled: August 29, 2013Date of Patent: November 6, 2018Assignee: Disney Enterprises, Inc.Inventors: Oliver Wang, Aljosa Smolic

Patent number: 10037615Abstract: This disclosure related to systems and methods of palette-based color editing. A set of principle colors may be identified from among individual colors of individual pixels of an image. Color distributions about the individual principle colors may be determined. An individual color distribution may include a homogenous range of colors that may vary with respect to an individual principle color. Pixels may be associated with one or more pixel groups based on correspondences between individual colors of the individual pixels and individual colors included in the individual color distributions corresponding to the individual pixel groups. Color editing may be effectuated by modifying colors of pixels in a given group independently from other colors of other pixels in other groups.Type: GrantFiled: July 1, 2016Date of Patent: July 31, 2018Assignees: Disney Enterprises, Inc., ETH ZURICHInventors: Yagiz Aksoy, Tunc Ozan Aydin, Marc Pollefeys, Aljosa Smolic

Patent number: 9997134Abstract: Methods and systems for calibrating devices reproducing high dimensional data, such as calibrating High Dynamic Range (HDR) displays that reproduce chromatic data. Methods include mapping input data into calibrated data using calibration information retrieved from spatial data structures that encode a calibration function. The calibration function may be represented by any multidimensional scattered data interpolation methods such as Thin-Plate Splines. To efficiently represent and access the calibration information in runtime, the calibration function is recursively sampled based on guidance dataset. In an embodiment, an HDR display may be adaptively calibrated using a dynamic color guidance dataset and dynamic spatial data structures.Type: GrantFiled: February 2, 2015Date of Patent: June 12, 2018Assignee: DISNEY ENTERPRISES, INC.Inventors: Aljosa Smolic, Nikolce Stefanoski, Tunc Ozan Aydin, Jing Liu, Anselm Grundhofer
