题目：On Poisson Vector Graphics: Authoring, Vectorization and Extension
摘要：Poisson vector graphics (PVG) is a new type of vector graphics with 4 salient features: 1) explicit separation of hue and tone, which greatly facilitates hue and tone editing; 2) more degrees of freedom (than the conventional diffusion curve images) to simulate photo-realistic rendering; 3) allowing (self-)intersecting primitives; and 4) native support seamless cloning with transparent or opaque background. In this talk, I demonstrate PVG as an intuitive and effective authoring tool through extensive examples. I also discuss the vectorization technique, which converts a natural image into editable Poisson vector graphics. Finally, I will talk about extending PVG from 2D Euclidean domains to 3D surfaces.
