Image contrast enhancing method for fluoroscopic apparatus e.g. scanner, involves producing detection card to reveal movements in spatial zone, between two dates, for balancing filter effect applied to one of two acquired images
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).
