<p>A method (1) of processing signals by means of rescaling, comprising the steps of: - downscaling (10) an initial signal (11), in accordance with a predetermined downscaling factor (Df) to obtain a downscaled signal (12), - upscaling (20), the downscaled signal (12) to obtain an upscaled signal (13) having the same dimensions as said initial signal (11), - comparing (30) the initial signal (11) and the upscaled signal (13) to calculate a comparison parameter, - if said comparison parameter is within a previously defined range, decreasing (50) the downscaling factor (Df) and repeating the steps of downscaling (10), upscaling (20) and comparison (30), - if said comparison parameter is outside the previously defined range, encoding (40) an encoded signal (14) as a function of the downscaled signal (12).</p> |
