Robust feature extraction method based on run-length compensation for degraded character recognition

Conventional features are robust for recognizing either deformed or degraded characters. Most conventional character recognition methods address either one or the other. This paper proposes a feature extraction method that is robust for both of them. Run‐length compensation is introduced for approxi...
