Abstract
Discrimination based on the photo-response nonuniformity (PRNU) is a powerful method for source camera identification. However, strongly-shrinked images tend to degrade the performance of the algorithm. To deal with this problem, we propose a PRNU-map reconstruction method from multiple scaled images. Experimental results show the effectiveness for heavily scaled images.
