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