Paper Abstract

The accurate form of image noise is helpful for noise- suppressing. The random process of 1/f noise is analyzed with wavelet functions and a Maximum Likelihood method is employed for finding the accurate power spectral density of 1/f noise. The signal is estimated effectively from noise image.
