摘要:
The present invention, an object display system, provides a system and method for positioning objects on a viewing area. One embodiment can be viewed as providing a method comprising the steps of specifying a plurality of objects, specifying a plurality of object pairs from the plurality of objects, specifying a potential function for each one of the specified object pairs, specifying a similarity value (s) for each one of the specified object pairs, determining an energy (e) for each one of the potential functions and solving for the minimum total energy (E) of the plurality of potential functions such that a distance (r) between each of the specified object pairs is determined.

A method and system thereof for computing forces on data objects in a physics-based visualization system are described. First forces exerted on a data object by other data objects in the plurality are determined without considering the similarity between data objects. Second forces exerted on the data object by a portion of the other data objects, each data object in the portion having a degree of similarity to the data object, are determined considering the similarity between data objects. The first forces are adjusted using the second forces to determine a net force on the data object. The net force is thus determined without having to consider similarity between all data objects in the plurality.

A method for visualizing high density graphical data sets for display is effectuated by determining the graphical density corresponding to an area of the display, where the graphical density is of a non-uniform nature. A non-linear visual space transformation corresponding to the graphical density is processed. Resolution in the area of the display is increased in response to the non-linear visual space transformation and the area is displayed with increased resolution.

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.

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.

Rendering 3D paintings can be done by compositing strokes embedded in space. Users input strokes and other image elements using an input device that specifies a 2D view of the element, and the system provides the 3D position of the element based on rules and processes, some of which allow for user input of high level parameters, thereby allowing for intuitive and quick entry of 3D elements, and a 3D scalar field. The artist can treat the full 3D space as a canvas. Strokes painted in a 2D viewport window are embedded in 3D space in a way that gives creative freedom to the artist while maintaining an acceptable level of controllability. The canvas need not be tied to any particular object already in a scene, but the canvas can be dependent on, or a function of, another object. An implicit canvas can be defined by the 3D scalar field.

A method of stimulating a deformable object comprises modeling deformable elasticity for the object by defining an actual shape and a goal shape and pulling points in the goal shape towards corresponding points in the goal shape.

A system for estimating a spacecraft (6) position is disclosed. It includes receiving stations (4) for receiving signals transmitted from the spacecraft (6) and a processing station (2) for receiving data from the receiving stations (4). Each receiving station (4) records, during a recording window (8), the signals transmitted from the spacecraft (6) and transmits, to the processing station (2), data representing the recorded signals during the recording window (8). The recording windows (8) associated with each of the receiving stations (4) are offset and/or of different size with respect to each other. The processing station (2) correlates the recorded signals to estimate the distance difference between the spacecraft (6) and each of a plurality of receiving stations and to estimate the spacecraft (6) position. A method, a receiving station (4), a processing station (2) and a computer program are also disclosed.

摘要:
A computer-implemented method for invariant-based normal estimation. The method includes calculating a set of measured invariants for a point associated with a surface of an object, where the set of measured invariants is based on pixel information that includes lighting information, calculating one or more sets of estimated invariants for the point associated with the surface of the object, where each set of estimated invariants is based on a known lighting environment for the object and a different normal for the point associated with the surface of the object, and determining a first normal for the point associated with the surface of the object that results in the set of measured invariants corresponding to a first set of estimated invariants.
