摘要
A method and apparatus for comparing (26) an infrared image of a person (12) to a database of visual images of persons (6) and calculating the probability that each is a match (42) to the infrared image is characterized by extracting minutiae from the infrared image and extracting visible minutiae from the visible images. Coincident minutiae which occur in both spectra are used to scale and register the infrared and the visible images. Other minutiae are spectrum-dependent (8), but must obey rules relative to minutiae of the other spectrum, due to the anatomical structure (34) of the human face and body. The primary application is for identification of persons seen in infrared surveillance imagery, using a reference database of visual images. Other applications includes compression of talking head video and animation of synthetic faces. The method and apparatus can also be applied to areas of the body other than the face, to compare images from different spectra including images from medical sensors.
