In a method for displaying a multispectral image, a plurality of target regions (T1, T2, T3, T4) is selected within an analysis window (FA), and a Fisher projection is performed separately for each target region in order to optimize a contrast in the multispectral image in the analysis window. Basic enhanced contrast images are thus obtained for all the target regions in the same analysis window, whereupon a combined image is formed from the basic images and is displayed on an image display unit.

Abstract
The invention relates to an alignment method based on a simplified mode allowing processing using an invariant Kalman filter, in which each speed involved in the navigation equations is expressed in a work reference frame (Rt) translated with respect to an inertial reference frame (Ri) and for which the origin moves along a reference inertial trajectory, the carrier of which is assumed to be close (geographic origin for alignment with the sun at known position, GPS trajectory for alignment in-motion, etc.). This simplified mode comprises the repetition of the following steps to estimate a mobile carrier state (P): - propagation (PROP) determining an estimated current state from a preceding estimated state, inertial sensor measurements and theoretical information on the carrier trajectory (P) - updating (MAJ) the estimated state using theoretical information on the carrier trajectory (P). The deterministic uncertainties of the sensors (bias/drift/scale factors, etc.) are only estimated during the propagation and update steps. A perturbation step (PERT) then allows inclusion of the values ignored in the simplified mode and estimation of these values by an optimisation method.
