ABSTRACT:Within the digital image processing, it is very difficult to determine which noise is present in an image as well as removal of noise. In this paper make use of various efficient filters as the proposed filters such as fuzzymean-median filter, alpha trimmed decision based median filter improves the quality of images. These proposed filters can easily remove Gaussian noise, salt and pepper noise and also mixed noise i.e. (Gaussian noise and salt and pepper). Various results of the proposed work are obtained by using parameters such as peak signal to noise ratio (PSNR), mean square error (MSE) and root mean square error (RMSE) which shows better performance.
KEYWORDS:Gaussian noise, impulse noise, Fuzzy-mean-median filter, Alpha trimmed decision based median filter, improved bilateral filter.
