    Abstract

    This report presents an application of image enhancement techniques in fingerprints as a tool for forensic sciences. Digital image processing technology was applied to restore fingerprints with non-uniform contrast. Whenever the results obtained by applying conventional enhancement techniques were not satisfactory, we combined spatial domain as well as frequency domain techniques in order to enhance the features that allowed later identification. The fingerprints correspond to a person who was murdered by military forces in 1976. The processed fingerprints where sent to the Court of Justice where forensic experts could finally find out the identity of a person who had been unknown until that moment.
