| Abstract: | On the basis of analyzing and comparing current vectorization methods of raster image and related softwares, a human-computer interactive vectorization method combining VP Studio software and CASS software is proposed, which includes automatic vectorization based on VP Studio and editing and post-processing based on CASS. Vectorization operations on about 30 raster images show that this method can evidently increase the efficiency of vectorization and reduce the labor intensity. |
