10-8 携帯カメラ入力による中国活字認識の基礎的検討(第10部門 メディア認識と評価II)

抄録

This paper investigates fundamental characteristics of mobile camera-based Chinese character recognition. For two kinds of typical OCR algorithms, we verify the influence to recognition accuracy of light source, font type and character resolution. Experimental results using Chinese restaurant menus show that contour features are more robust for environmental changes than skeleton features.
