Abstract
This creative component implements a small example of a simple comparison between two measures used to compute the camera fingerprint. We compare the performance between the regular Pearson correlation coefficient and the Hamming distance, a faster but less accurate measure. The results are presented using two cameras, and displaying the classification using a confusion matrix of correctly identified and incorrectly identified test images. Our results support the paper by Bayram et al (2012) that the Hamming measure can produce similar accuracy results to the Pearson.
