Abstract
The Photo-Response Non-Uniformity (PRNU) has been recently introduced as a powerful tool to detect image forgeries. In spite of its effectiveness in many scenarios, the proposed method fails to detect small manipulations. In this work we propose a modified version of the detection algorithm described in, based on a preliminary segmentation of the image, which guarantees a better detection performance for small size additive forgeries.
