Improvement of Image Deblurring Through Different Methods
A.Anusha A.Anusha · IOSR Journal of Computer Engineering · 2013
In this paper, we analyze the research on this topic both theoretically and experimentally through different methods the deterministic filter; Bayesian estimation, the conjunctive deblurring algorithm (CODA),and alpha tonal correction method which performs the deterministic filter and Bayesian estimation in in a conjunctive manner.We point out the weakness of the deterministic filter and unify the limitation latent in two kinds of Bayesian estimators..The proposed algorithm, alpha tonal correction methods, which gives better performance than the deterministic filter and sharp image estimation.We point out the weaknesses of the deterministic filter and unify the limitation latent in two kinds of image estimation methods.I further explain proposed alpha correction method which can able to handle quite large blurs beyond deterministic filter and image estimation.Finally, I demonstrate that our method outperforms state-of-the-art methods with a large margin.
