    44This demo shows how to use image correlation to measure a displacement versus time (instead of velocity). Open the image UVMAT_DEMO06_displacement (accessible on http://servforge.legi.grenoble-inp.fr/pub/soft-uvmat/).

    16  * mode displacement, with respect the origin index 1 (first image by default). Then the menu for choosing image pairs desappears, as the correlation for each image are done with respect to the reference one, taken as origin for the displacement.

    1717 * Correlation box fairly large 31 corresponding to a coarse pattern, and considering that spatial resolution is not critical.
    1818 * Large search 107 need to capture the max displacement
