Document images undergo various degradation processes. Numerous models of these degradation processes have been proposed in the literature. In this paper we propose a model-based restoration algorithm. The restoration algorithm rst estimates the parameters of a degradation model and then uses the estimated parameters to construct a lookup table for restoring the degraded image. The estimated de...

A restoration scheme for images that are corrupted with both blur and impulsive noise is proposed in this paper to reconstruct an image minimum degradation. The consists of two stages sequence where the first stage applied blurred second de-blurred has been subject through electronic transmission. uses frequency domain filtering while utilizes spatial reduce indicated noise, respectively. In pa...
