We propose a two-state Markov chain model of degraded document images. The model generates random and burst noise to simulate isolated pixel reversal as well as blurring of a larg...

A single parameter value that represents the difference between the original and the digitized characters is determined from a binary scan of a test chart. It represents the combi...
