摘要： A tool for inbetweening is provided, wherein inbetween frames are at least partly computer generated by analyzing elements of key frames to identify strokes, determining corresponding stroke pairs, computing a continuous stroke motion for each stroke pair, defined by a carrier defined by endpoints of the two strokes and, for mutual endpoints, adjusting the continuous stroke motion of the meeting strokes such that the adjustment results in the continuous stroke motion coinciding at the mutual endpoint such that the mutual endpoint would follow the same path and deforming the stroke as it is moved by the stroke motion, wherein the deformation is a weighted combination of deformations, each reconstructed using shape descriptors that are interpolated from the shape descriptors of the corresponding samples on the key frames, wherein the shape descriptors are computed from neighboring sample points in the cyclic order of samples along the stroke.

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： A method and system for segmenting tubular structures in 3D images is disclosed. User inputs identifying a first region on the image inside of a tubular structure and a second region of the image outside of the tubular structure are received. Based on this information, an ordered series of pearls are generated along the tubular structure. Pearls are spheres, each having a center location and a radius determined based on the center locations and radii of previous pearls and on local voxel intensities in the image. A continuous model of the tubular structure can be generated by interpolating the center locations and radii of the ordered series of pearls. The ordered series of pearls can be displayed and easily edited in response to user input, thus providing an efficient and flexible method for interactive segmentation of a potion of interest in a tubular structure.

摘要： Embodiments facilitate the production of a B-spline curve that approximates a set of N-dimensional (position, pressures, tilt, etc.) discrete input samples recorded by a digital input device. Iterative noise filtering and B-spline subdivision processes are performed within a dynamic window of recent samples. A vector representation is produced at interactive rates after each new sample is captured, thus producing results that are comparable to what the same artist would expect if drawing on paper.

摘要： A method and system for segmenting tubular or stroke-like structures in 2D images is disclosed. Examples of such structures include, but are not limited to, blood vessels, bones, roads, rivers, electrical wirings, and brush-strokes. User inputs identifying a first region on the image inside of a tubular structure and a second region of the image outside of the tubular structure are received. Based on this information, an ordered series of pearls are generated along the tubular structure. Pearls are 2D disks, each having a center location and a radius determined based on local pixel intensities in the image. A continuous model of the tubular structure is generated by interpolating the center locations and radii of the ordered series of pearls.

摘要： 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.

摘要翻译： 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。
