Abstract
En 中文
We present a technique for creating an editable vector graphic from an object in a raster image. Object selection is performed interactively in subsecond time by calling graph cut with each mouse movement. A renderable mesh is then computed automatically for the selected object and each of its subobjects by (1) generating a coarse object mesh; (2) performing recursive graph cut segmentation and hierarchical ordering of subobjects; (3) applying error-driven mesh refinement to each (sub)object. The fully layered object hierarchy compares favorably with current approaches and is computed in a few 10s of seconds, facilitating object-level editing without leaving holes.
