Image Watermarking for Tamper Detection
We propose an oblivious watermarking technique for tamper detection in digital images. By comparing correlation values from different portions of the image, the technique enables us to distinguish malicious changes, such as replacing / adding features from nonmalicious changes resulting from common image processing operations. The technique can be implemented with small memory and computational...
متن کاملThe Combinational Use Of Knowledge-Based Methods and Morphological Image Processing in Color Image Face Detection
The human facial recognition is the base for all facial processing systems. In this work a basicmethod is presented for the reduction of detection time in fixed image with different color levels.The proposed method is the simplest approach in face spatial localization, since it doesn’trequire the dynamics of images and information of the color of skin in image background. Inaddition, to do face...

متن کاملImage Tamper Detection Using Non Alignment of Jpeg Grids
Digital images have a very significant role in various fields like criminal and forensic investigations, medical imaging and journalism. But due to wide availability of powerful editing software, image forgery has become much easier. The aim of this paper is to detect the forgery on JPEG compressed images when splicing (copy-paste) will result in non alignment of JPEG grids. JPEG is widely used...
متن کاملNonintrusive Image Tamper Detection Based on Fuzzy Fusion
In this paper, we propose a novel fuzzy fusion of image residue features for detecting tampering or forgery in video sequences. We suggest use of feature selection techniques in conjunction with fuzzy fusion approach to enhance the robustness of tamper detection methods. We examine different feature selection techniques, the independent component analysis (ICA), and the canonical correlation an...
