Natural Image Statistics for Digital Image Forensics Siwei Lyu We describe a set of natural image statistics that are built upon two multi-scale image decompositions, the quadrature mirror filter pyramid decomposition and the local angular harmonic decomposition. These image statistics consist of first-and higher-order statistics that capture certain statistical regularities of natural images. We propose to apply these image statistics, together with classification techniques, to three problemsdoi:10.1007/978-1-4614-0757-7_8 fatcat:lkqex5gjhzfzziiozqsmni6hku
