Source Camera Linking Algorithm Based on the Analysis of Plain Image Zones

Abstract

This paper proposes an image linking scheme, where the plain zones of the image under analysis are used, which are detected using the Discrete Cosine Transform. Then, a Block Matching 3D denoising filter is used to reduce the additive noise such that the residual error of the plain zones. The Peak to Correlation Energy is applied to compare the enhanced residual noise patterns. Experimental results show that the proposed methodology compared to conventional techniques is better due to the emphasis on plain zones, because the detailed and edge areas introduce distortions that can significantly affect the extracted residual noise patterns.
