摘要： 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.

摘要： 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.

摘要： 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.
摘要翻译：渲染3D绘画可以通过合成嵌入在空间中的笔画来完成。用户使用指定元素的2D视图的输入设备输入笔画和其他图像元素，并且系统基于规则和过程提供元素的3D位置，其中一些允许用户输入高级参数，从而允许用于直观和快速地输入3D元素，以及3D标量字段。艺术家可以将完整的3D空间视为画布。在2D视口窗口中绘制的笔画嵌入在3D空间中，可以为艺术家创造自由，同时保持可接受的可控性水平。画布不需要绑定到场景中已经存在的任何特定对象，而画布可以依赖于另一个对象的功能。隐式画布可以由3D标量字段定义。

摘要： 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.

摘要： Systems, methods, and devices for operating a multiplex wireless local area network using separated uplink and downlink channels in the 802.11 and television white space (TVWS) spectra are disclosed. Opportunistic detection and use of available TVWS frequency channels allows for fixed and mobile wireless devices to more efficiently use the available wireless bandwidth. By using separated uplink and downlink channels, a fixed wireless device can listen to incoming uplink frames from other mobile and fixed wireless devices and monitor for uplink frame collisions. In the event of an uplink frame collision, the fixed wireless device can immediately send a stop frame in the downlink channel to all involved wireless devices to avoid lost channel time due to the delay caused by most acknowledgement-based collision recovery protocols. Similarly, communicating mobile and fixed wireless devices can transmit and receive data frames in both directions simultaneously.

摘要： Where images are displayed such that unintended light is also included and that light cannot be fully subtracted from the displayed image, an image processor compensates by compensating for the remaining light using perceptual models. In some cases, the perceptual model includes a plurality of user sensitivities and computation is performed, at least in part, based on expected user sensitivity to light pollution in portions of the images. The perceptual model might include a contrast sensitivity function, threshold-vs-intensity, saliency prediction and visual masking. The model might include artist indications of view attention. A light pollution likelihood map might be used to reduce the amount of computation needed, using a likelihood measure to determine an amount of computation to perform.
