Moreover, an improved version of the
locally adaptive discrete cosine transform (LADCT) filter is proposed in the filtering
stage to reduce the effect of scene details on noise residues. Finally, the post-estimation
stage consists of combining the PRNU estimated from each colour plane aims to reduce
the effect of colour interpolation and increasing the amount of physical PRNU
components. The aforementioned techniques have been assessed on two image datasets
acquired by several camera devices. Experimental results have shown a significant
improvement obtained with the proposed enhancements over related state-of-the-art
systems. Nevertheless, in this thesis the experiments are not including images taken with
various acquisition different resolutions to evaluate the effect of these settings on PRNU
performance.
