| Abstract(in English) | Stroke directional features are effective for recognizing handwritten Kanji characters. PDC and ePDC were proposed as one of the best directional features for Kanji. But ePDC is local shape descriptions of individual strokes and so is not robust against slanting, rotation, and the fluctuation in stroke direction seen in freely handwritten characters. Against this distortion, we propose the new features, named RDC/nRDC, which express the relative angle and the relative position as the 2-D relationship between strokes. Experiments show that the proposed new features achieve very high recognition rates of about 96% for ETL9B and are effective for recognizing handwritten Kanji characters. |
