In this paper, we introduce a new method for removing noise from digital images, based on statistical model of wavelet coefficients. We use two-dimensional generalized autoregressive conditional heteroscedasticity (GARCH) model for statistical modeling of wavelet coefficients. Using two-dimensional GARCH model yields a novel wavelet coefficients model, which is capable of taking into account important characteristics of wavelet coefficients, such as non-stationarity, heavy tailed marginal… CONTINUE READING
