Investigation on Restoration and Assessment Method of Digital Image with Strong Impulse Noise
摘要
Abstract
In order to solve the problems existed in restoration and objective quality assessment method of digital image with strong pulse noise,employing the theory of a certain extent of noise elimination for the spatial filters,a gray image restoration algorithm of strong impulse noise based on pixel processing theory is presented on the basis of investigations on the strong pulse noise data representation and restoration method.It represents the denoising degree parameter of the restoration quality assessment method has been defined by the given formula of the error signals and decomposes the color image into the three color components of R,G,B respectively with RGB model,and the modified method has been proposed which makes gray image restoration algorithm used in components directly.The experimental results show that the proposed algorithm can not only restore gray image with strong impulse noise,but also apply to color image based on RGB model without a large quality of the sort operations,which has advantages of fast execution and stable restoration effect,and that the definition of denoising parameter can accurately supply the objective assessment of restoration quality.关键词
