Abstract

A method is shown in this paper to calculate the possible character recognition error rate, which is originated from the optical transfer functions and sampling performance of the scanner. The increase of the possible reading error is the result of the image degradation through the optical transfer, and can be measured by the so-called similarity error. Theoretical and experimental results are in a good accordance. The different character types, scanners and printer outputs can be characterized by this method, as well.
