-This paper presents a filter for restoration of Dental images that are highly corrupted by salt and pepper noise and
speckle noise, Poisson noise. After detecting and correcting the noisy pixel, the proposed filter is able to suppress noise level.
In this paper for each noise proposed different type of filter and compare these three types of filter with their PSNR value and
MSE value and SNR value. After filtering stage maximum detected noise pixels will be filtered and simulation results show
the filtered image.
