This paper presents an algorithm of connected components based on combination of equivalent run-lengths.Through calculating the connected components of the background area of character image,hole features of a handwritten character image can be extracted.In order to combine correlative run-lengths with a connected component,an equivalent array is constructed to record and transfer the relationship of the connectivity of run-lengths.The results obtained from the test for handwritten numeral image show that the algorithm can capture the features of handwritten numeral characters accurately and efficiently and this method can be used to classify characters.
