The invention relates to a method for determining reproducibly if visual features of an object are known to a person. For that purpose, one or more test images are prepared by applying predetermined algorithms by means of which an image of the respective object is altered such that cognitive perception is in general impossible whereas the global affective impression is not influenced. Said test images are presented to a person and it is determined if recognition occurs and if so how certain and how correct. Finally, it is determined which parts of the original images can be reproduced based on information recalled from the memory and if there is confusion or interchange with other images.

L'invention concerne un procédé servant à déterminer de façon reproductible si les caractéristiques visuelles d'un objet sont connues d'une personne. Ceci consiste à préparer une ou plusieurs images test par application d'algorithmes prédéterminés modifiant l'image de l'objet respectif, de sorte que la perception cognitive est, en général, impossible, tandis que l'impression affective globale n'est pas influencée; à présenter lesdites images test à une personne et à déterminer si la reconnaissance s'effectue et, si c'est le cas, à quel niveau de certitude et de précision; enfin, à déterminer les parties des images originales qui peuvent être reproduites en fonction des informations rappelés de la mémoire ou s'il y a une confusion ou un échange avec d'autres images.
