<p>In order to transform an input digital signal (xn) into one or more output digital signals (yn) containing even-indexed samples (y2n) and odd-indexed samples (y2i+n), this filtering method includes at least one iteration (506) which contains an operation of modifying even-indexed samples (y2n) by a function (R) of weighted odd-indexed samples ( alpha 0,j.y2n+mj) and an operation of modifying odd-indexed samples (y2n+1) by means of a function (R) of weighted even-indexed samples ( beta 0,j.(y2n - y2n+2)). The weighted samples are obtained by means of at least one weighting operation. At least one of the weighting operations is applied to the difference between two consecutive even-indexed samples. Application to the processing of images. <IMAGE></p> |
