Shape Description and Recognition of Digital Map Symbols

Huang Wenqian (Dalian Naval Academy, Dalian,Liaoning, 116018)  
It is an important research content of Cartography to use map automatic digitization instead of old way by hand which is a difficult and time consuming task. The description and recognition of digital map symbols is a key technique to realize this objective. In this paper, a traditional boundary following is improved by using a new algorithm with a criterion to control search. A describes symbols method is proposed by use Fourier coefficient. The way how to calculate these coefficients from chain code is given. Then the calculation formula is further ameliorated. And how to extract shape feature invariant from Fourier coefficient is introduced also. At last some symbols recognition experiments are done, and relevant analysis is discussed.
