Source Camera Identification Issues [PDF]

International Journal of Digital Crime and Forensics, 2011
Statistical image features play an important role in forensic identification. Current source camera identification schemes select image features mainly based on classification accuracy and computational efficiency. For forensic investigation purposes; however, these selection criteria are not enough.
