Abstract: Digital images provide sufficient information in various real world applications. But it is quite impossible to avoid quality degradation during image transmission process due to interruption of noise . Since the type and behaviour of the noise changes for different fields, thus plenty of denoising approaches are applied by the researchers to retrieve the quality of the image. This paper provides a thorough survey of various well known denoising methods used in spatial and frequency domain.
