In this age of digitization, digital images are used as a prominent carrier of visual
information. Images are becoming increasingly ubiquitous in everyday life. Unprecedented …

Resampling detection is one of the most important topics in image forensics, and the most
widely used method in resampling detection is spectral analysis. Since JPEG is the most …

The forensic analysis of resampling traces in upscaled images is addressed via subspace
decomposition and random matrix theory principles. In this context, we derive the asymptotic …

Performance of camera identification methods based on PRNU is very sensitive to geometric
operations applied to images during acquisition and processing. Handling images that have …

In image processing and machine vision, corner detection is pivotal in diverse applications,
including computer vision, 3D reconstruction, face detection, object tracking, and video …

Gamma transformation plays an important role in image processing and image display.
However, images may look either bleached out or too dark if transformed with improper …

Resampling detection is a helpful tool in multimedia forensics; however, it is a challenge
task in cases with compression and noisy. In this paper, by modeling the recovery of edited …

Image forensics technology based on image manipulation detection has aroused great
interest of researchers in recent decades. By revealing the traces of image manipulations, it …

Recent research has employed deep learning to detect intake gestures from inertial sensor
and video camera data. However, the fusion of these modalities has not been attempted …

Edge is composed by a collection of its nearby pixels which has a step change or changes
in roof, an image is an information system and most of its information comes from the edges …
