In this paper, we focus on studying the effects of various image operations on sensor fingerprint camera identification. It is known that artifacts in the image processing pipeline, such as pixel defects or unevenness of the responses in the CCD array as well black current noise leave telltale footprints. Nowadays, camera identification based on the analysis of these artifacts is a well established...
A novel color-based two-step, coarse-to-fine video replica detection system is proposed in this paper. The first step uses an R-tree in order to perform a coarse selection of the database (original) videos that potentially match the query video. A training procedure that utilizes attacked versions of the database videos and aims at achieving robustness to attacks is being used. A frame-based voting...
