Claim:
A computer-implemented method for determining the suitability of a digitized image of a person for person identification, with the steps: segmenting the image of a person into a background area and a head or face area, analyzing the head or face area to determine at least one geometric feature and at least one reproduction feature, comparing the at least one geometric feature and the at least one reproduction feature with at least one predetermined threshold value, making a determination of the suitability of the image based on a result of the comparison, performing image correction when the determination of the suitability results is an image that does not fulfill one or more quality criteria, wherein the image correction comprises: correcting at least one image reproduction feature in the entire image and/or the head or face area and/or the background area, correcting at least one geometric feature of a head or face area displayed in the image of a person, wherein the at least one geometric feature comprises a size and/or shape and/or position and/or spatial orientation of the head or face area within the image of a person, and wherein the at least one reproduction feature comprises a contrast and/or a color distribution and/or a sharpness of the image and/or a brightness and/or a grade of staining and/or a measure for the irradiation of the head or face area.
