We are currently on a verge of a revolution in digital photography. Developments in
computational imaging and adoption of artificial intelligence have spawned new editing …

With the development of sophisticated image editing and manipulation tools, the originality
and authenticity of a digital image is usually hard to determine visually. In order to detect …

Many forensic techniques have recently been developed to determine whether an image
has undergone a specific manipulation operation. When multiple consecutive operations are …

This paper proposes a splicing forgery detection method with two parts: a coarse-to-refined
convolutional neural network (C2RNet) and diluted adaptive clustering. The proposed …

As a retouching manipulation, contrast enhancement is typically used to adjust the global
brightness and contrast of digital images. Malicious users may also perform contrast …

Image inpainting, an image processing technique for restoring missing or damaged image
regions, can be utilized by forgers for removing objects in digital images. Since no obviously …

Image forensics has attracted wide attention during the past decade. However, most existing
works aim at detecting a certain operation, which means that their proposed features usually …

Image forgery detection has aroused widespread research interest in both academia and
industry because of its potential security threats. Existing forgery detection methods achieve …

Over the past decade, many efforts have been made in passive image forensics. Although it
is able to detect tampered images at high accuracies based on some carefully designed …

Median filtering is used as an anti-forensic technique to erase processing history of some
image manipulations such as JPEG, resampling, etc. Thus, various detectors have been …
