Multifeature Fusion Detection Method for Fake Face Attack in Identity Authentication

Table 4

Compared the fusion algorithm of this experiment to NLBP and LK optical flow.

Sample	TP	TN	Accuracy	Dimension
NLBP	92.78%	93.34%	93.12%	59
LK optical flow	94.33%	91.17%	95.19%	128
Fusion feature	97.03%	96.88%	97.56%	24

TP, the real input is accepted; TN, the fake input is refused.
