Claim One:
1. method of processing a digitized image consisting of a table T of numbers x (ij) each expressing the degree of luminosity of a corresponding pixel (i, j), the method comprising the reduction of high-frequency noise by the following steps: a) decomposing the table T into a continuous series of p basic tables of the same dimensions each having n pixels, b) ordering the data from the series of basic tables into a processing table X of p rows and n columns, each row i being formed of the ordered sequence of the pixels from the i th basic table, d) effecting a multivariate statistical analysis on the processing table X, considering the n columns as variables, to extract therefrom n representative factors, f) generating a reconstituted processing table XR of numbers xr (i, j) using only the first q representative factors and restoring the absolute degree of luminosity, then generating a reconstituted table TR constituting the reconstituted digitized image in which the high-frequency noise has been reduced in this way, wherein, during the step f), the reconstituted processing table XR is reconstituted by reconstructing each row i independently of the others, taking into account only the factors having a meaningful weight with the row i.
