Method for fusing images and apparatus therefor
First Claim
1. A method for forming a composite image from N source images where N is greater than one comprising the steps of:
- (a) decomposing each source image IN into a plurality L of sets of oriented component patterns PN (m, L), where m is the number of patterns in each of the L sets for the Nth source image;
(b) computing a saliency measure SN (m, L) for each component pattern PN (m, L);
(c) selecting component patterns from the component pattern sets PN (m, L) using the saliency measures SN (m, L) for each component pattern to form a set of oriented component patterns Pc (m, L) of the composite image; and
(d) constructing the composite image from the set of oriented component patterns Pc (m, L).

Abstract
A method for fusing two or more source images to form a composite image with extended information content 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. Apparatus for fusing two or more source images to form a composite image is also disclosed.
