This paper focuses on a novel model for digital suppression of semi-transparent blotches, caused by the contact between water and paper of antique documents. The proposed model is based on laws regulating the human visual system and provides a fast and automatic algorithm both in detection and restoration. Experimental results show the great potentialities of the proposed model in solving also critical situations.

The proposed model is based on laws regulating the human visual system and provides a fast and automatic algorithm both in detection and restoration.
