According to this method, for the formulation and recording of the retrieval data, each of the images (2) taking the form of a two-dimensional array of rows and columns of pixels, the image is divided into blocks (4) of pixels, each block (4) comprising pixels of at least two rows and two columns, retrieval data are calculated for each block (4) on the basis of at least the image data contained in the pixels of this block (4) and the retrieval data calculated is recorded in the form of at least one pixel (5) exhibiting a value dependent on the retrieval data.
Selon ce procédé, pour l'élaboration et l'enregistrement des données de restauration, chacune des images (2) se présentant sous la forme d'un réseau bidimensionnel de lignes et de colonnes de pixels, on divise l' image en blocs (4) de pixels, chaque bloc (4) comprenant des pixels d'au moins deux lignes et deux colonnes, on calcule pour chaque bloc (4) des données de restauration à partir d'au moins les données d'image contenues dans les pixels de ce bloc (4) et on enregistre les données de restauration calculées sous la forme d'au moins un pixel (5) présentant une valeur fonction des données de restauration.
