Abstract

The method involves acquiring two images (It-1, I-t) corresponding to a same spatial zone, at two dates (t-1, t) respectively. A detection card (Mt) with dimensions same as that of the image (It) is produced to reveal movements occurred in the zone, between the dates. The card is used for producing a processed image related to the image (It). The card is used to balance an effect of filter applied to the image (It).
