A Survey on Image Denoising Algorithms(IDA)

[摘要] Very few traditional noise removal algorithms provide appreciable results in producing denoised images. The hyper spectral images and SAR (Synthetic Aperture Radar) Images are severely affected due to different kind of noises. Several denoising procedures are proposed to preserve the image quality in textured images by removing the noise encountered .In this paper the effective noise removal techniques are discussed for various types of images and the suggestions for improving the interpretability or the perception of information in the image are listed.
