Identification of Digital Elevation Annotation in Scanned Map
According to analyzing the features of annotation of spot elevation,this paper gives a method of identifying elevation annotation of a scanned topographic map and discusses the principle of the method,including separating character series on the basis of morphologic translating and cutting apart single character on the basis of vertical projecting.Finally,there is a performance evaluation.
