Abstract: The application of Morphological processing in character recognition is discussed in this paper. Morphological processing technologies such as opening operation and closing operation are used to enhance the images to eliminate the touching and broken characters. Experiment recults show that morphological processing in character recognition can repair the character-touching and character-broken images effectively, and then improve the accuracy of character recognition.
Keywords: morphological processing; character recognition; Halcon
