Calibration and validation by professional observers of the Mission-Quality criterion for imaging systems design.

Imaging systems comparisons remains today a sensitive subject because of the difficulty to merge radiometric and spatial dimensions into a single, easy to use, parameter. By leaning explicitly on professional image users and their requirements we show how to build such a criterion, called Mission-Quality. A specific observation campaign is described and its results are used to calibrate and carry first proof of the criterion adequacy.

Radiometric order preserving method to display wide-dynamic images for imagery photointerpretation.

Wide-dynamic numerical images are increasingly frequent in professional environments, military photointerpretation, and x-ray or magnetic resonance medical imagery. However, a dynamic compression process is necessary to exploit such images without incessant image manipulation. A wealth of efficient methods has been developed to tackle this problem on aesthetic grounds.
