With advanced image journaling tools, one can easily alter the semantic meaning of an
image by exploiting certain manipulation techniques such as copy clone, object splicing …

The advent of high-tech journaling tools facilitates an image to be manipulated in a way that
can easily evade state-of-the-art image tampering detection approaches. The recent …

Resampling is an important signature of manipulated images. In this paper, we propose two
methods to detect and localize image manipulations based on a combination of resampling …

In the classical bilateral filter, a fixed Gaussian range kernel is used along with a spatial
kernel for edge-preserving smoothing. We consider a generalization of this filter, the so …

Today, images editing software has greatly evolved, thanks to them that the semantic
manipulation of images has become easier. On the other hand, the identification of these …

JPEG is the most commonly used image compression standard. In practice, JPEG images
are easily subject to blocking artifacts at low bit rates. To reduce the blocking artifacts, many …

Realistic image forgeries involve a combination of splicing, resampling, cloning, region
removal and other methods. While resampling detection algorithms are effective in detecting …

Image degradation damages genuine visual structures and causes pseudo structures.
Pseudo structures are usually present with regularities. This letter proposes a machine …

Image quality assessment has been a topic of recent intense research due to its usefulness
in a wide variety of applications. Owing in large part to efforts within the HVEI community …

When the compression quality factor (QF) is low, JPEG images are usually accompanied by
very severe block artifacts. The conventional image deblocking models based on low-rank …
