Patent number: 8885021Abstract: 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: GrantFiled: January 10, 2012Date of Patent: November 11, 2014Assignee: Disney Enterprises, Inc.Inventors: Thomas Oskam, Alexander Hornung, Huw Bowles, Kenny Mitchell, Markus Gross

Publication number: 20140327674Abstract: The disclosure provides an approach for estimating depth in a scene. According to one aspect, regions where the depth estimation is expected to perform well may first be identified in full-resolution epipolar-plane images (EPIs) generated from a plurality of images of the scene. Depth estimates for EPI-pixels with high edge confidence are determined by testing a number of discrete depth hypotheses and picking depths that lead to highest color density of sampled EPI-pixels. The depth estimate may also be propagated throughout the EPIs. This process of depth estimation and propagation may be iterated until all EPI-pixels with high edge confidence have been processed, and all EPIs may also be processed in this manner. The EPIs are then iteratively downsampled to coarser resolutions, at which edge confidence for EPI-pixels not yet processed are determined, depth estimates of EPI-pixels with high edge confidence made, and depth estimates propagated throughout the EPIs.Type: ApplicationFiled: July 17, 2013Publication date: November 6, 2014Inventors: Alexander SORKINE-HORNUNG, Changil KIM, Henning ZIMMER, Yael PRITCH, Markus GROSS

Publication number: 20140219550Abstract: Estimating a pose of an articulated 3D object model (4) by a computer is done by •obtaining a sequence of source images (10) and therefrom corresponding source image segments (13) with objects (14) separated from the image background; •matching such a sequence (51) with sequences (52) of reference silhouettes (13?), determining one or more selected sequences of reference silhouettes (13?) forming a best match; •for each of these selected sequences of reference silhouettes (13?), retrieving a reference pose that is associated with one of the reference silhouettes (13?); and •computing an estimate of the pose of the articulated object model (4) from the retrieved reference pose or poses. The result of these steps is an initial pose estimate, which then can be used in further steps, for example, for maintaining local consistency between pose estimates from consecutive frames, and global consistency over a longer sequence of frames.Type: ApplicationFiled: May 8, 2012Publication date: August 7, 2014Applicant: LIBEROVISION AGInventors: Tiberiu Popa, Marcel Germann, Richard Keiser, Markus Gross, Remo Ziegler

Patent number: 8766982Abstract: 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: GrantFiled: July 26, 2010Date of Patent: July 1, 2014Assignee: Disney Enterprises, Inc.Inventors: Gioacchino Noris, Alexander Hornung, Robert Sumner, Maryann Simmons, Markus Gross

Patent number: 8717390Abstract: An integrated system and method 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: May 6, 2014Assignee: Disney Enterprises, Inc.Inventors: Markus Gross, Alexander Hornung, Manuel Lang, Philipp Kraehenbuehl

The display assembly includes at least one light emitting device and may include, but does not require, a modulating device used in conjunction according to display methods taught herein to display light field data. A display assembly controller may be used to render a light field with depth into a multi-planar plenoptic display assembly by assigning decomposed portions of the light field to the display assembly for display or presentation by differing ones of the emitting elements and by operating a modulating device to provide a parallax barrier. In one embodiment, a dynamic parallax barrier and a number of bi-state screens. Another embodiment uses a beam splitter to co-locate two pairs of autostereoscopic displays each including a projector projecting 3D content, a parallax barrier, and an emissive/projector element.Type: GrantFiled: July 18, 2011Date of Patent: February 4, 2014Assignee: Disney Enterprises, Inc.Inventors: Nicola V.

Patent number: 8633926Abstract: Techniques are provided for mesoscopic geometry modulation. A first set of mesoscopic details associated with an object is determined by applying a filter to an image of an object. Mesoscopic details included in the first set of mesoscopic details are detectable in the image of the object and are not detectable when generating a coarse geometry reconstruction of the object. A three-dimensional model for the object is generated by modulating the coarse geometry with the first set of mesoscopic details.Type: GrantFiled: January 18, 2010Date of Patent: January 21, 2014Assignee: Disney Enterprises, Inc.Inventors: Thabo Dominik Beeler, Bernd Bickel, Markus Gross, Robert Sumner, Paul Beardsley

Patent number: 8624891Abstract: Techniques are disclosed for performing image space reprojection iteratively. An insignificant parallax threshold depth is computed for a source image. Portions of the image having depth values greater than the insignificant parallax threshold depth may be shifted uniformly to produce corresponding portions of the reprojection (target) image. An iterative fixed-point reprojection algorithm is used to reproject the portions of the source image having depth values less than or equal to the insignificant parallax threshold depth. The fixed point reprojection algorithm quickly converges on the best pixel in the source image for each pixel in a target image representing an offset view of the source image. An additional rendering pass is employed to fill disoccluded regions of the target image, where the reprojection algorithm fails to converge.Type: GrantFiled: January 17, 2011Date of Patent: January 7, 2014Assignee: Disney Enterprises, Inc.Inventors: Huw Bowles, Kenny Mitchell, Robert Sumner, Wojciech Jarosz, Markus Gross
