Detection statistics for the Neyman-Pearson detector (14) (images (a) and (c), the corresponding scale is ×105) and the Normalized Correlation coefficient detector (19) (images (b) and (d)) on a set of 190 images (Nikon D7000 camera), where the PRNU is estimated from the first 50 images (top row) or the first 25 images (bottom row). From the results, it is clear that the detector is able to identify which images were used to estimate the PRNU, but its performance decreases when more images are employed in the estimation, as the contribution of each individual image gets diluted when larger datasets are considered
