Abstract
Aiming to improve gray image quality, especially in an OCR (optimal character reader) or a FAX, we have studied noise reduction methods using a hybrid Kalman filter that accompanies an auto-correlation method. Experimental results show that the proposed method gets higher quality than conventional noise reduction methods.
