Publication number: 20130335426Abstract: Techniques are presented for controlling the amount of temporal noise in certain animation sequences. Sketchy animation sequences are received in an input in a digital form and used to create an altered version of the same animation with temporal coherence enforced down to the stroke level, resulting in a reduction of the perceived noise. The amount of reduction is variable and can be controlled via a single parameter to achieve a desired artistic effect.Type: ApplicationFiled: June 15, 2012Publication date: December 19, 2013Applicant: DISNEY ENTERPRISES, INC.Inventors: Gioacchino NORIS, Daniel SYKORA, Stelian COROS, Alexander HORNUNG, Brian WHITED, Maryann SIMMONS, Markus GROSS, Robert SUMNER

Publication number: 20130241934Abstract: A method is provided for sketch segmentation via smart scribbles, the results of which are especially suitable for interactive real-time graphics editing applications. A vector-based drawing may be segmented into labels based on input scribbles provided by a user. By organizing the labeling as an energy minimization problem, an approximate solution can be found using a sequence of binary graph cuts for an equivalent graph, providing an optimized implementation in a polynomial time suitable for real-time drawing applications. The energy function may include time, proximity, direction, and curvature between strokes as smoothness terms, and proximity, direction, and oriented curvature between strokes and scribbles as data terms. Additionally, the energy function may be modified to provide for user control over locality control, allowing the selection of appropriately sized labeling regions by scribble input speed or scribble input pressure.Type: ApplicationFiled: March 19, 2012Publication date: September 19, 2013Applicant: DISNEY ENTERPRISES, INC.Inventors: Gioacchino Norris, Daniel Sykora, Ariel Shamir, Stelian Coros, Alexander Hornung, Robert Sumner, Maryann Simmons, Brian Whited, Markus Gross

Patent number: 8514932Abstract: Systems, methods and articles of manufacture are disclosed for performing scalable video coding. In one embodiment, non-linear functions are used to predict source video data using retargeted video data. Differences may be determined between the predicted video data and the source video data. The retargeted video data, the non-linear functions, and the differences may be jointly encoded into a scalable bitstream. The scalable bitstream may be transmitted and selectively decoded to produce output video for one of a plurality of predefined target platforms.Type: GrantFiled: February 8, 2010Date of Patent: August 20, 2013Assignee: Disney Enterprises, Inc.Inventors: Nikolce Stefanoski, Aljosa Smolic, Yongzhe Wang, Manuel Lang, Alexander Hornung, Markus Gross

Publication number: 20130176397Abstract: A method is provided for an optimized stereoscopic camera with low processing overhead, especially suitable for real-time applications. By constructing a viewer-centric and scene-centric model, the mapping of scene depth to perceived depth may be defined as an optimization problem, for which a solution is analytically derived based on constraints to stereoscopic camera parameters including interaxial separation and convergence distance. The camera parameters may thus be constrained prior to rendering to maintain a desired perceived depth volume around a stereoscopic display, for example to ensure user comfort or provide artistic effects. To compensate for sudden scene depth changes due to unpredictable camera or object movements, as may occur with real-time applications such as video games, the constraints may also be temporally interpolated to maintain a linearly corrected and approximately constant perceived depth range over time.Type: ApplicationFiled: January 10, 2012Publication date: July 11, 2013Applicant: DISNEY ENTERPRISES, INC.Inventors: Thomas Oskam, Alexander Hornung, Huw Bowles, Kenny Mitchell, Markus Gross

Publication number: 20130057644Abstract: Techniques are disclosed for generating autostereoscopic video content. A multiscopic video frame is received that includes a first image and a second image. The first and second images are analyzed to determine a set of image characteristics. A mapping function is determined based on the set of image characteristics. At least a third image is generated based on the mapping function and added to the multiscopic video frame.Type: ApplicationFiled: August 31, 2012Publication date: March 7, 2013Applicant: DISNEY ENTERPRISES, INC.Inventors: Nikolce Stefanoski, Aljoscha Smolic, Manuel Lang, Miquel À.

Patent number: 8373802Abstract: Techniques are provided for content-aware video retargeting. An interactive framework combines key frame-based constraint editing with numerous automatic algorithms for video analysis. This combination gives content producers a high level of control of the retargeting process. One component of the framework is a non-uniform, pixel-accurate warp to the target resolution that considers automatic as well as interactively-defined features. Automatic features comprise video saliency, edge preservation at the pixel resolution, and scene cut detection to enforce bilateral temporal coherence. Additional high level constraints can be added by the producer to achieve a consistent scene composition across arbitrary output formats. Advantageously, embodiments of the invention provide a better visual result for retargeted video when compared to using conventional techniques.Type: GrantFiled: September 1, 2009Date of Patent: February 12, 2013Assignee: Disney Enterprises, Inc.Inventors: Markus Gross, Alexander Hornung, Manuel Lang, Philipp Kraehenbuehl

Publication number: 20120206473Abstract: Techniques are disclosed for controlling robot pixels to display a visual representation of a real-world video texture. Mobile robots with controllable color may generate visual representations of the real-world video texture to create an effect like fire, sunlight on water, leaves fluttering in sunlight, a wheat field swaying in the wind, crowd flow in a busy city, and clouds in the sky. The robot pixels function as a display device for a given allocation of robot pixels. Techniques are also disclosed for distributed collision avoidance among multiple non-holonomic and holonomic robots to guarantee smooth and collision-free motions.Type: ApplicationFiled: April 27, 2012Publication date: August 16, 2012Inventors: Paul BEARDSLEY, Javier Alonso MORA, Andreas BREITENMOSER, Federico PERAZZI, Alexander HORNUNG

Publication number: 20110175916Abstract: An animation system can vectorize an image by generating, from an input drawing, a dataset corresponding to vector and digital representations of the input drawing such that a rendering engine could render an image having features in common with the input drawing from the representations, as a collection of strokes and/or objects rather than merely a collection of pixels having pixel color values. A vectorizer might receive an input image, generate a particle clustering data structure from a digitization of the input image, generate a stroke list, wherein strokes in the stroke list correspond to clusters of particles represented in the particle clustering data structure, generate a graph structure that represents connections between strokes on the stroke list, and determine additional characteristics of a stroke beyond the path of the stroke, additional characteristics being stored such that they correspond to strokes. The strokes might be generated using global topology information.Type: ApplicationFiled: July 26, 2010Publication date: July 21, 2011Applicant: Disney Enterprises, Inc.Inventors: Gioacchino Noris, Alexander Hornung, Robert Sumner, Maryann Simmons, Markus Gross
