Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for providing sketch segmentation via smart scribbles, the method comprising: retrieving user sketch data comprising a plurality of strokes; receiving at least one input scribble for segmenting the user sketch data; minimizing an energy function for assigning at least one of a plurality of labels to the plurality of strokes, the energy function having: a data term measuring an affinity between the plurality of strokes and the at least one input…
