摘要：

The aim of this work is to restore an image from a fusion of two X-ray images. A pair of images of a same scene are obtained using two stacked films of different sensitivities. The response function of the first film presents an undesirable nonlinear shape. Nevertheless, the second image is strongly degraded by both noise and large stains, whereas the first one is not. The original problem which initiated our study was to combine these images in order to estimate a unique image free of noise and stains and expressed in the gray scale of the second film. To perform it, we must estimate the transfer function between the response functions of the two films and remove the stains of the second image. (C) 1996 Academic Press, Inc.
