Revealing Traces of Image Resampling and Resampling Antiforensics

Table 3

(%) of each detector on detecting forged resampled images from unaltered images. Here “without” means without applying JPEG compression on test images. The best result is displayed by bold texts.

	JPEG compression	Proposed FD	FM [12]	FE [11]
Upscaled versus unaltered	Without	0.13	5.13	3.30
	QF = 95	1.40	8.20	6.90
	QF = 80	6.10	18.47	15.47
Downscaled versus unaltered	Without	0.13	11.33	16.60
	QF = 95	3.70	16.27	20.20
	QF = 80	16.0	32.10	30.80
Rotated versus unaltered	Without	0.20	8.93	8.13
	QF = 95	0.90	12.70	12.30
	QF = 80	6.67	26.40	27.47
