Abstract:

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.
