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 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.
