Drawing capturing system using image enhancement
N. Nakamura, K. Hosaka, M. Nagura · 2002
The paper describes the properties of Ueda's (1985) image enhancement method for line drawings and its merit for practical use. This method can remove the line discontinuities or mis-connections caused by scanning errors. The method is applied to simple images to evaluate its effect quantitatively. The authors confirm that it is more efficient than any other methods, and propose a drawing capturing system based on this method that can build up high quality drawing databases faster than any other system.
