An image processing method comprising the step of processing an input signal to generate an adjusted output signal, wherein the intensity values I(x,y) for different positions (x,y) of an image are adjusted to generate an adjusted intensity value I'(x,y) in accordance with :(I) where Pi( gamma ) is an orthogonal basis of functions of gamma defined in the range 0< gamma <1 ; and Qi (..) are antiderivatives of (II) or an approximation thereto, LPFΩ[..] is an operator of low-pass spatial filtering ; Ωi is a cut-off frequency of the low-pass filter, and F(..) is a weighting function. |
