Please provide two images for the purpose of extracting and conducting a comparative analysis of their camera sensor pattern noise. Employing the Photo Response Non-Uniformity (PRNU) as the fundamental characteristic, the images will undergo assessment utilizing the Peak-to-Correlation Energy (PCE) as the metric for similarity.
When the PCE exceeds a threshold of 100, it implies a significant likelihood that the source devices of the queried images are identical. Furthermore, an elevated PCE value signifies an increased probability that the queried images originate from a common source.
