A new estimation approach of resampling factors using threshold-based peak detection

This paper proposes a new method for digital image forensics using threshold-based peak detection to estimate interpolation factor. We describe how resampling introduces periodic correlations, and to detect these correlation using the differential method along the horizontal, vertical and diagonal d...

Summary:This paper proposes a new method for digital image forensics using threshold-based peak detection to estimate interpolation factor. We describe how resampling introduces periodic correlations, and to detect these correlation using the differential method along the horizontal, vertical and diagonal direction, respectively.
