Improvement of Image Quality by AddingWhite Gaussian Noise

[摘要] When we discuss about image processing, major topics include intensity transformations, spatial filtering, frequency-domain filtering, image restoration and reconstruction, geometric transformations and image registration, colour image processing, wavelets, image compression, morphology, image segmentation, image representation and description, and object recognition. In our presentation we deal with the different ways of representing the image by adding white gaussian noise.
