Use Map EstimationFor Image Sharpening
Journal Title: IOSR Journals (IOSR Journal of Computer Engineering) - Year 2014, Vol 16, Issue 1
Abstract
This paper presents a various paradigms for estimating a single latent sharp image given multiple blurry and/or noisy observations. Whether employing it to make an unusable image good, a good image better or giving a great image that extra edge, it produces unparalleled sharpening and deblurring results that add distinction and definition. From a blurred image to recover a sharp version is a long-standing inverse problem. We point out the weaknesses of the deterministic filter and unify the limitation. Theoretically and experimentally we analyze image deblurring through three paradigms are: 1) The filter determination 2) Estimation by Bayesian 3) Alpha tonal correction methods. The resulting paradigms, which require no essential tuning parameters, can recover a high quality image from a set of observations containing potentially both blurry and noisy examples, without knowing a priori the degradation type of each observation. Our goal is to reveal the limitations and potentials of recent methods when dealing with quite large blurs and severe noise. Experimental results on both synthetic and real-world test images clearly demonstrate the ability to produce a desired or intended result of the proposed method.
