fuzziness primitives recognition relevant feedback
A prototype of sketch-based graphic input tool is realized for drawings management,which is based upon online graphic fuzzy recognition and relevante feedback.A method to locate breakpoints of freehand drawings by using curvature and speed information in a stroke is described.After definition of geometrical recognition features of primitive objects and considering the ambiguity of sketch that causes a problem about understanding user’s retrieval intention precisely in sketch retrieval,the fuzzy membership function is designed and the membership degree is calculated for recognizing primitive objects.The distance between two fuzzy sets can be used to reveal user’s latent retrieval requirement.The algorithm is partly applied in the system of engineering drawings management system.The application results show that the method of sketch-based graphic input and fuzzy recognition described here has good value in engineering application.
