Abstract :
An efficient method is developed to reconstruct broken handwritten digits. The extracted structural points and smoothed skeletons are used to describe the structure of a broken handwritten digit. The broken points of the digits are preselected, based on the minimum distance between the "end" points of two neighboring segments. The correction rules of the preselected broken points are designed, based on an analysis of the structure and skeleton of the digits, and digit reconstruction is made based on the found broken points. Experimental results are given to show the effectiveness of the method.
