DOI: 10.1111/1365-2478.13032
Abstract: ABSTRACT Erratic noise often has high amplitudes and a non‐Gaussian distribution. Least‐squares–based approaches therefore are not optimal. This can be handled better with non–least‐squares approaches, for example based on Huber norm which is computationally expensive.… read more here.

DOI: 10.1111/1556-4029.70161
Abstract: A forensic analyst must utilize a variety of artifacts in order to create a potent forensic method. By eliminating these artifacts, anti‐forensic approaches seek to elude forensic detectors. The field of digital image forensics has… read more here.
