    • 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.

    • 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.
    • 动画系统可以通过从输入图形生成对应于输入图形的向量和数字表示的数据集来矢量化图像,使得渲染引擎可以从表示形式呈现具有与输入图形共同的特征的图像,作为 笔画和/或对象的集合,而不仅仅是具有像素颜色值的像素的集合。 向量化器可以接收输入图像,从输入图像的数字化生成粒子聚类数据结构,生成笔画列表,其中笔画列表中的笔画对应于在粒子聚类数据结构中表示的粒子簇,生成图形结构 其表示笔划列表上的笔画之间的连接,并且确定笔划的额外特征超出笔画的路径,附加特征被存储使得它们对应于笔画。 可以使用全局拓扑信息生成笔画。

    • In an animation processing system, generating images to be viewable on a display using a computer that are generated based on scene geometry obtained from computer readable storage and animation data representing changes over time of scene geometry elements, but also images can be modified to include shading that is a function of positions of objects at other than the current instantaneous time for a frame render such that the motion effect shading would suggest motion of at least one of the elements to a viewer of the generated images. Motion effects provide, based on depiction parameters and/or artist inputs, shading that varies for at least some received animation data, received motion depiction parameters, for at least one pixel, a pixel color is rendered based on motion effect program output and at least some received scene geometry, such that the output contributes to features that would suggest the motion.

    • 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. Once the drawing is labeled, a wide range of drawing applications are enabled.
    • 提供了一种通过智能涂鸦进行草图分割的方法,其结果特别适用于交互式实时图形编辑应用。 基于矢量的绘图可以基于用户提供的输入涂鸦来分割成标签。 通过将标签组织为能量最小化问题,可以使用等效图形的二进制图形切割序列找到近似解决方案,在适合实时绘图应用的多项式时间内提供优化的实现。 能量函数可以包括笔画之间的时间,接近度,方向和曲率,作为平滑度项,以及作为数据项的笔划和笔迹之间的接近度,方向和取向曲率。 此外,可以修改能量函数以提供用户对局部性控制的控制,允许通过涂抹输入速度或涂抹输入压力来选择适当尺寸的标签区域。 一旦绘图被标记,就可以使用各种绘图应用程序。
