Comparison of facial methods.

	LBPH	SVM	CNN
Advantages	It recognizes both the frontal and side view of faces	It works well with high-dimensional data	It automatically detects features without human supervision
Disadvantage	With large-scale databases, the histograms produced are too long and increase computation time	When using a large database, the training time can be too much. The overlapping classes can decrease the accuracy	Accuracy decreases when images have different poses, backgrounds, and lighting
