Patent number: 11140440Abstract: Novel systems and methods are described for creating, compressing, and distributing video or image content graded for a plurality of displays with different dynamic ranges. In implementations, the created content is “continuous dynamic range” (CDR) content—a novel representation of pixel-luminance as a function of display dynamic range. The creation of the CDR content includes grading a source content for a minimum dynamic range and a maximum dynamic range, and defining a luminance of each pixel of an image or video frame of the source content as a continuous function between the minimum and the maximum dynamic ranges. In additional implementations, a novel graphical user interface for creating and editing the CDR content is described.Type: GrantFiled: May 2, 2019Date of Patent: October 5, 2021Assignee: Disney Enterprises, Inc.Inventors: Aljoscha Smolic, Alexandre Chapiro, Simone Croci, Tunc Ozan Aydin, Nikolce Stefanoski, Markus Gross

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: 10699396Abstract: Systems and methods are disclosed for weighting the image quality prediction of any visual-attention-agnostic quality metric with a saliency map. By accounting for the salient regions of an image or video frame, the disclosed systems and methods may dramatically improve the precision of the visual-attention-agnostic quality metric during image or video quality assessment. In one implementation, a method of saliency-weighted video quality assessment includes: determining a per-pixel image quality vector of an encoded video frame; determining per-pixel saliency values of the encoded video frame or a reference video frame corresponding to the encoded video frame; and computing a saliency-weighted image quality metric of the encoded video frame by weighting the per-pixel image quality vector using the per-pixel saliency values.Type: GrantFiled: February 1, 2018Date of Patent: June 30, 2020Assignee: Disney Enterprises, Inc.Inventors: Tunc Ozan Aydin, Nikolce Stefanoski, Aljoscha Smolic, Mark Arana

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: 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

Patent number: 9979895Abstract: Embodiments herein disclose a tone mapping system that generates a base layer by filtering a frame in an HDR video. The tone mapping system then generates a tone curve using a tone mapping parameter derived from the base layer—e.g., a mean or maximum luminance value. Once the tone curve parameter is identified, the system performs temporal filtering to smooth out inconsistencies between the current value of the tone curve parameter and the values of tone curve parameter of at least one previous frame in the HDR video. The tone mapping system applies the temporally filtered tone curve to the base layer to generate a temporally coherent layer. The temporally coherent base layer can be combined with a detail layer derived from the HDR video to generate a frame of a tone mapped video.Type: GrantFiled: November 25, 2015Date of Patent: May 22, 2018Assignees: Disney Enterprises, Inc., ETH Zurich (Eidgenoessische Technische Hochschule Zurich)Inventors: Aljosa Aleksej Andrej Smolic, Tunc Ozan Aydin, Simone Maurizio Croci, Nikolce Stefanoski
