The aim of this survey is to provide a comprehensive overview of the state of the art in the
area of image forensics. These techniques have been designed to identify the source of a …

Image forensics is an investigation of digital images to identify manipulations that have been
done on them. Nowadays, due to the availability of different low-cost devices for capturing …

For decades, photographs have been used to document space-time events and they have
often served as evidence in courts. Although photographers are able to create composites of …

Nowadays advanced image editing tools and technical skills produce tampered images
more realistically, which can easily evade image forensic systems and make authenticity …

It is often desirable to determine if an image has been modified in any way from its original
recording. The JPEG format affords engineers many implementation trade-offs which give …

In this paper, we explore transformed spaces, represented by image illuminant maps, to
propose a methodology for selecting complementary forms of characterizing visual …

Fake news and deep fakes have been making social and mainstream media headlines. At
the same time, engaged scientists strive for finding ways to detect forgeries and suspicious …

When creating a photographic composite, it can be difficult to match lighting conditions. We
describe a technique for measuring lighting conditions in an image, and describe its use in …

The advent of sophisticated photo editing software has made it increasingly easier to
manipulate digital images. Often visual inspection cannot definitively distinguish the …

We describe a method for detecting physical inconsistencies in lighting from the shading
and shadows in an image. This method imposes a multitude of shading-and shadow-based …
