| Abstract(in English) | This paper proposes a method for recognizing low-quality characters in scene images captured by a digital camera. Characters degraded by different illuminatio conditions and intensity variation are hardly recognized when templates with an individual character is used. Especially, small characters as'l'or'r'are hardly recognized. To cope with the problem on such degradation, this paper employs the displacement matching and templates with neighboring characters of a focused character. The templates including information on neighboring characters of a focused one improve the recognition accuracy for these degraded characters. Also, the displacement matching reduces segmentation error caused by degradation. Experiments with 3, 468 characters in 9 images show that this method achieves a recognition rate of 96.3%, higher than 88.4% of templates without neighboring characters. |
