摘要: Abstract Given a set of rough strokes drawn by an artist (either in pen-paper medium or digital medium) raster format, the objective is to group them meaningfully and represent with simple most appropriate curves. In this paper, Delaunay triangulation based algorithm proposed for grouping strokes. The procedure capable identifying open curves reconstructing broken helping user masking misinterpreted regions. We also introduce shape aware skeleton smoothing which best approximates taking input sketch as reference create final vector output. can control combines techniques computational geometry well image processing utilize power both.
