| Abstract: | The digitization for engineering record curves is very important for the digital storage, reuse, share and exchange of these curves. The authors propose a new method for automatic detection and data restoration of graph drawing curves with the theory and technology of image processing and pattern recognition. The method includes the intersecting curve separation based on medial axis transformation, the seed restoration based on spatial-frequency information fusion, and the disconnected curve detection based on second order differentiation. The advantages of this method are the fast computation, high automatization and intelligence. |
