This paper discusses the use of character images to determine the parameters of an image degradation model. The acute angles in character images provide information used to find ...
Document images undergo various degradation processes. Numerous models of these degradation processes have been proposed in the literature. In this paper we propose a modelbased r...
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...
This paper presents a new enhanced text extraction algorithm from degraded document images on the basis of the probabilistic models. The observed document image is considered as a...
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...
