Francis Labaere, Pieter Vuylsteke: Image contrast enhancing method. Agfa Gevaert, Richard J Birch, February 10, 1998: US05717791 (54 worldwide citation)

A contrast enhancing processing method is disclosed that is based on a transformation of an original image into a multiresolution edge representation based on a wavelet transform. The multiresolution edge representation is modified and subsequently subjected to a reconstruction procedure. Different ...

Allouche Cyril: 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. Ge Med Sys Global Tech Co, December 3, 2004: FR2855638-A1

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 ...
