A Novel Method to Segment Keyboard Characters and Symbols Using Morphology
Xinwen Gao, Xing Jian Guan · Advanced materials research · 2013
This paper proposed a novel method to segment the keyboard characters and symbols. An algorithm based on mathematical morphology has been applied to the keyboard inspection system. By using various morphology operations like opening and dilation, the algorithm overcomes the disadvantages of the traditional method such as time-consuming and unreliable. Therefore, our approach is capable of segmenting the characters and symbols accurately and we at last get the region of interest (ROI) to represent the keyboard characters and symbols.
