摘要: A prototype system for encoding chemical structure diagrams from scanned printed documents is described. The distinguishes a diagram other material on page image using size and spacing characteristics. It line graphics symbols in an intermediate vectorization stage. Line information mapped into connection that represents atomic bonds. Atomic are identified by means of drawing conventions optical character recognition. final coded output interfaces to conventional chemistry software database storage retrieval, publishing, modeling. >
