Abstract: A method for processing an acquired image (IA) showing a structured personal document (D) including a visual inspection zone (VIZ). The method includes determination of a first character string from an automatic reading zone or of barcode type (MRZ) of predetermined format, the first character string representing personalised information specific to the owner of the document (D), generation from the first character string of an intermediate image (IS) showing a second character string representing the same personalised information, detection in the acquired image of a third character string in the visual inspection zone (VIZ), representing the same personalised information, the detection comprising an overall comparison of the intermediate image (IS) with the acquired image, location in the visual inspection zone (VIZ) of a region of interest containing the third character string.

Abstract: The invention relates to a method for analyzing a structured document likely to be deformed from a first image and a second image of the document, comprising steps of: matching first points of interest extracted in the first image with second points of interest of a reference image showing a model of the document, estimation of a first geometric transformation taking account of deformations of the structured document shown in the first image relative to the model from the matches, determination of at least one first region to be analyzed in the first image, by projection of at least one reference region of the reference image by means of the first transformation, analysis of the content of the first determined region, matching third points of interest extracted in the second image with fourth points of interest extracted in the first image, estimation, from the matches made in the preceding step, of a second geometric transformation taking account of deformations of the document shown in the second image r
