Systems and methods for the rapid analysis of images that are particularly useful in avionic contexts are provided. One specific method describes steps of computing algorithmic complexity and/or logical depth, so as to rapidly categorize objects, comprising images and/or points of interest determined in these images, according to discrete levels of structuring, organization or order. Complex image processing operations may then concern restricted subsections of the images. The complexity or logical depth computing operations may for example comprise steps of losslessly compressing the objects row by row and/or column by column, of determining statistical distributions of the compression rates of these objects, of determining one or more scores on the basis of the compression rates or of statistical moments and of locally or globally categorizing one or more received images. Developments describe system and software aspects.

Rapid analysis of images

A dual harmonization method for a worn head-up display system for making the display of piloting information of an aircraft on a display conform with the outside real world includes a step of acquisition of N measurements {circumflex over (K)}of head posture detection by a series of sightings Vi corresponding to images oriented according to orientations Oi of one and the same photograph taken by a camera, secured to and aligned with the attitude inertial device D, then a step of joint computation of the matrices of relative orientation Mand Mas joint solutions of the dual harmonization &#xdb;=&#x11c;&#xb7;{circumflex over (K)}&#xb7;{circumflex over (D)}, i varying from 1 to N, in which &#xdb;is the transpose of the matrix M(image(i)/0) of relative orientation of the image(i) of rank i relative to the display D, with Mand Mrespectively equal to the right and left matrices {circumflex over (D)} and &#x11c;. A worn head-up display system is configured to implement the dual harmonization method.
