Abstract:
In this paper an efficient standard deviation based algorithm which can automatically detect, localize and extract tampered area from tampered images is presented. The proposed approach is based on the application of a color reduction technique; Intensity based method for edge detection, and the localization of tampered regions using horizontal and vertical edges. This paper is based on the fact that normally tampered regions process high standard deviation compared to non tampered regions. The outputs of the algorithm are tampered regions. The performance of the approach is demonstrated by presenting promising experimental results for a set of images taken from different types of video sequences.
