| Abstract: | An automatic recognition system for characters on numeric meter dial plate displayed by LED is introduced. First, at the stage of character extraction, the approach of color extraction is used for extracting characters when the characters color is as same as background but has difference in brightness. Second, at the step of character segmentation, gain method is adopted for deciding characters edges and segmenting characters more accurately. Besides, the combination of statistics and scan approaches is used for recognizing characters. Finally, a series of experiments are made and experimental results show that the proposed scheme is feasible and has great robustness. |
