<p>In noise measurement for video sequences it is difficult to distinguish between picture content and noise. In order to improve the measurement reliability the results ( sigma p1, sigma p2, sigma p3) of two different noise level computing methods are combined. One computation relies on the analysis of displaced field or frame differences (DFD), the other is based on the values of the field or frame differences (FD) over static picture areas. <IMAGE></p> |
