Matching of faces in camera images and document photographs

An automatic system for the person identification based on comparison of a camera image and a document photo presents several design difficulties. The main complication arises from the fact that the document photo may represent quite a different appearance of the test person, i.e., an older version, sometimes by years, or with a different hairstyle, facial expression and lighting conditions. In addition the scanned photo is usually of a much lower quality. In this paper elements of a system for a face comparison between camera images and archival photo albums are discussed and experimental results are given. Such a system may be instrumental for document control or for police investigations
