Conference paper


After a large scale of a natural or manmade disaster or fatal accident is hit all victims have to be immediately and accurately identified for the sake of relatives or for judicial aspects. Also it is not ethical for human being to lose their identities after death. Therefore, the identification of a person after or before death is a big issue in any society. In most commonly used methods for person identification includes utilization of different biometric modalities such as Finger-print, Iris, Hand-Veins, Dental biometrics etc. to identify humans. However only a little has been known the chest X-Ray biometric which was very powerful method for identification especially during the mass disasters in which most of other biometrics are unidentifiable. Therefore, in this paper, we propose an identification method which utilizes a fusion of computed tomography and radiography imaging processes to identify human body after death based on chest radiograph database taken prior to death. To confirm the validity of the proposed approach we exhibit some experimental results by using real life dataset. The outcomes are more promising than most of existing methods.
