Automated interpretation and editing of fuzzy line drawings

Abstract

One of the problems in automated line drawing analysis is to construct a cleaner drawing from the original drawing. For example, a chemist using an interactive chemical structure analysis system will usually draw a rough sketch of a chemical structure on a display device or a tablet. It is desirable to obtain a cleaner version of the rough sketch so that the cleaner drawing can be redisplayed. Moreover, the cleaner drawing can then be used to generate hard-copy output through a plotter, a magnetic film recorder or a photocomposer. Such an automated line drawing editing program can enhance the usefulness of an interactive system and is also of value in itself.
