Space-scale-frequency representation and fixed chosen noise restoration (image)

We propose an image restoration with fixed chosen noise. We tune the threshold of wavelet packets coefficients in homogeneous areas by taking into account the noise signal dependance and the modulation transfer function of the optic instrument.< >
