Temporal Forensics and Anti-Forensics for Motion Compensated Video

Forensics, Anti-forensics and Counter Anti-forensics for JPEG Compressed Images

-With the advancement in information technology and image processing software the manipulation of the images has increased considerably from past few decades. Retouching or tampering of the images has been so prevalent that nowadays one can hardly believe their originality. Image authenticity is done using forgery detection techniques. These methods are broadly classified as active and passive....

Fast Motion Compensated Temporal Interpolation for Video

Recently, MPEG-4 is being formed to study very-low-bit-rate(VLBR) video coding for applications in videotelephony. In this paper, we propose a possible postprocessing technique for VLBR coding. In videophone applications, temporal subsampling is a simple technique which can be combined with other compression schemes to achieve very large compression ratio, so as to satisfy the VLBR requirement....

Title of dissertation : DIGITAL MULTIMEDIA FORENSICS AND ANTI - FORENSICS Matthew

Title of dissertation: DIGITAL MULTIMEDIA FORENSICS AND ANTI-FORENSICS Matthew C. Stamm, Doctor of Philosophy, 2012 Dissertation directed by: Professor K. J. Ray Liu Department of Electrical and Computer Engineering As the use of digital multimedia content such as images and video has increased, so has the means and the incentive to create digital forgeries. Presently, powerful editing software...

Motion Codec Ant Forensics

This paper designs an anti-forensics technique for video files. In this technique the frames are extracted from the video and extracted frames are analysed by using the total variation and the Q. The relation of the total variation and the Q is used to get whether particular frame is dithered or not. The simulation is carried out on the video downloaded from the internet and analysed by using t...
