Digital Image Processing is processing on the digital images by means of different algorithms. A
digital image can be of different types such as RGB, grayscale, radiographic images etc. All kind of images
have some of noise (s) captured by capturing devices because of atmospheric conditions, incorrect photon count
because of electromegnetic interference etc. This study is based on radiographic image denoising with several
techiques in spatial domain, frequency domain, wavelet domain. This study presentsthe result of comparitive
study on different filters available in different domains and their PSNR values. This study shows the effect of
mask size on each filter and thus gives an idea for the proper selection of size of mask (square) for a filter to
get better result.
Key words: Filters, global soft thresholding, MSE , PSNR , spatial and frequency domain, wavelet,
