| Abstract: | A comprehensive review is presented for the development of the anisotropic diffusion(AD) in image noise reduction.The various AD models are classified into two categories: the one for normal noise reduction and the other for speckle noise reduction.During the development of the AD technique,several typical models are highlighted in their principle,method and characteristics.From experiments,the performances of these AD models are comprehen-sively compared in terms of noise reduction,edge localization and st... |
