Abstract

A method for fusing two or more source images to form a composite image with extended information content which may be color augmented and apparatus for forming the composite image from the source images is disclosed. Each source image is decomposed into a number of source images of varying resolution. The decomposed source images are analyzed using directionally sensitive operators to generate a set of oriented basis functions characteristic of the information content of the original images. The oriented basis functions for the composite image are then selected from those of the different source images and the inverse of the decomposition performed to construct the composite image. Color augmentation provides information as to the relative weighting of the contribution of each source to the composite image.
