Abstract: To generate a pixel-accurate depth map, data from a range-estimation sensor (e.g., a time-of flight sensor) is combined with data from multiple cameras to produce a high-quality depth measurement for pixels in an image. To do so, a depth measurement system may use a plurality of cameras mounted on a support structure to perform a depth hypothesis technique to generate a first depth-support value. Furthermore, the apparatus may include a range-estimation sensor which generates a second depth-support value. In addition, the system may project a 3D point onto the auxiliary cameras and compare the color of the associated pixel in the auxiliary camera with the color of the pixel in reference camera to generate a third depth-support value. The system may combine these support values for each pixel in an image to determine respective depth values. Using these values, the system may generate a depth map for the image.

Abstract: An automated machine wherein messages exchanged between components of the machine are forwarded to at least one component at a first time point that temporarily stores them and from that component to a central unit at a second time point is disclosed. Said first time point preceding said second time point within the framework of a cycle time of the automated machine. The time points are determined relative to that cycle time and provided to respective components in conjunction with a startup of the automated machine. The component temporarily storing messages forwards them in the manner of a layer-3 switch. This message forwarding is driven by the respective time points, rather than event-driven, can operate seamlessly in existing systems wherein communications are time-slot controlled, and decouples the components so that real-time communications within the machine can be optimized.

Abstract: 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.

Abstract: A method of animation of surface deformation and wrinkling, such as on clothing, uses low-dimensional linear subspaces with temporally adapted bases to reduce computation. Full space simulation training data is used to construct a pool of low-dimensional bases across a pose space. For simulation, sets of basis vectors are selected based on the current pose of the character and the state of its clothing, using an adaptive scheme. Modifying the surface configuration comprises solving reduced system matrices with respect to the subspace of the adapted basis.

Abstract: A closed-loop control system for stereoscopic video capture is provided. At least two motorized lenses are positioned in accordance with specified parameters to capture spatially-disparate images of a scene. The motorized lenses focus light on a corresponding one of the at least two sensors, which generate image streams. One or more processors execute instructions to provide a stream analyzer and a control module. The stream analyzer receives the image streams from the sensors and analyzes the image streams and the specified parameters in real time; the stream analyzer then modifies the image streams and generates metadata. The control module then receives and analyzes the image streams and metadata and transmits updated parameters to a control mechanism that is coupled to the at least two motorized lenses. The control mechanism then modifies operation of the at least two motorized lenses in real time in accordance with the updated parameters.

Abstract: A computer-implemented method is provided for physical face cloning to generate a synthetic skin. Rather than attempt to reproduce the mechanical properties of biological tissue, an output-oriented approach is utilized that models the synthetic skin as an elastic material with isotropic and homogeneous properties (e.g., silicone rubber). The method includes capturing a plurality of expressive poses from a human subject and generating a computational model based on one or more material parameters of a material. In one embodiment, the computational model is a compressible neo-Hookean material model configured to simulate deformation behavior of the synthetic skin. The method further includes optimizing a shape geometry of the synthetic skin based on the computational model and the captured expressive poses. An optimization process is provided that varies the thickness of the synthetic skin based on a minimization of an elastic energy with respect to rest state positions of the synthetic skin.

Abstract: Methods and systems for generating stereoscopic content with granular control over binocular disparity based on multi-perspective imaging from representations of light fields are provided. The stereoscopic content is computed as piecewise continuous cuts through a representation of a light field, minimizing an energy reflecting prescribed parameters such as depth budget, maximum binocular disparity gradient, desired stereoscopic baseline. The methods and systems may be used for efficient and flexible stereoscopic post-processing, such as reducing excessive binocular disparity while preserving perceived depth or retargeting of already captured scenes to various view settings. Moreover, such methods and systems are highly useful for content creation in the context of multi-view autostereoscopic displays and provide a novel conceptual approach to stereoscopic image processing and post-production.

Abstract: A multi-planar plenoptic display assembly with multiple spatially-varying light emitting and modulating planes. The display assembly includes at least one light emitting device and may include 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 projector is used with bi-state screens. In another embodiment, two automultiscopic displays (either parallax barrier or lenticular lenses) are overlaid with a beam splitter. In a further embodiment, an oscillating mirror is used to temporally and optically move one automultiscopic layer (either parallax barrier or lenses) through space.
