Image ForensicsImage Forensics is a rather young field of research that
plays an
important role in the field of digital forensics due to
today's fast
growing availability of digital footage. Digital image
data
can be
tampered in an easy and low-cost fashion. Relevant
objects
may be
removed from or added to the depicted scene, and thus new
photographic
evidence can be produced. This creates a need for expert
assessment that
indisputably distinguishes forgeries and original images.
Computer-assisted methods are able to obtain relevant
information e.g.
from distinctive traces on the data level or based on
inconsistencies in
the depicted scene or the image formation process.In this research project, the current state of the art is
to
be advanced
in several ways. Currently available methods are
evaluated
and improved
based on real forgery data. For this, an elaborate image
manipulation
dataset is created and maintained. Furthermore, new
methods
are to be
developed that concentrate on the physical consistency of
the depicted
scene. Properties like illumination and cast shadows are
to
be estimated
in a robust fashion to assess the consistency of the
depicted scene. | Project manager: PD Dr.-Ing. Christian Riess
