Development and exploitation of technology have led to the further expansion and
complexity of digital crimes. On the other hand, the growing volume of data and …

Image forensics is essential for detecting image manipulation, authenticating images, and
identifying sources of images. A forensic analyst can make use of various artifacts to develop …

Smooth filtering, a common blurring and denoising operator, has often been utilized
postoperatively to diminish the traces left by malicious manipulations. Most of the existing …

When it comes to reducing impulsive noise from digital photos, the Median Filter (MF) is a
nonlinear filter that can be employed effectively. This nonlinear filter is used to erase traces …

Median filtering is a widely used method for denoising and smoothing regions of an image; it
has drawn much attention from researchers of image forensic. A new detection scheme of …

Median filtering forensics for small-size JPEG compressed images is practicable and useful
in the block-based tampering detection. In this paper, we concentrate the detection of …

Median filtering (MF) is frequently applied to conceal the traces of forgery and therefore can
provide indirect forensic evidence of tampering when investigating composite images. The …

Median filtering (MF), a non-linear smoothing operation, has often been utilized as a means
of image denoising to protect image edges and hide the traces of image tampering …

For the detection of median filtering (MF) forensics, this paper proposes the feature vector
extracted from the bit-planes slicing of the forged image. The assembled feature vector is …

Median filtering is a widely used method for removing noise, preserving edges and
smoothing regions within an image. Detection of median filtering has drawn much attention …
