<p>The method consists in computing a luminance and/or chrominance gradient indicator (Ig) at each point of the image, in computing a threshold value (S(Xo)) as a function of each gradient obtained, in measuring the inter-image luminance and/or chrominance difference of each point of the image, in comparing the inter-image difference obtained at each point with the corresponding computed threshold value, in applying the result of the comparison to the input of a density-filtering device in order to detect the density of moving points in proximity to each scanned point and to compare the density obtained in respect of each point with a predetermined density threshold value in order to provide an indication of moving points when the density at each point considered exceeds the predetermined density threshold value.</p> |
