Digital Analysis, Comparison, and Projection of Fingerprints: A New Digital Device for Crime Scene Investigation

John Zheng Wang, PhD

Abstract


 

Since the mid-1990s, the forensic science community and law enforcement agencies have been using electronic/digital imaging devices such as video cameras, digital cameras, scanners, Power Point, and Adobe Photoshop software in crime scene recording. This paper introduces the Digital Imager in analyzing, comparing, and projecting fingerprint evidence. The portable device (software is included) can provide some unique functions: a larger field of view, longer zooming range, image dividing, and special viewings modes (of emboss, negative, edge, and grayscale effects). It is highly recommended that the new digital imaging device be utilized in fingerprint elimination and identification for crime scene investigation and courtroom presentation due to its multiple functions in one digital device.
