Merits and demerits of various face detection techniques.

Techniques	Merits	Demerits
Haar cascade algorithm [4]	Lesser false alarm part; improved feature extraction	Complex to implement
Geometric based algorithm [100]	Effective approach; easy implementation	Low accuracy; more false alarms
Viola–Jones algorithm with composite features [102]	High accuracy rate and low false detection rate	Sensitive to illumination variations
Improved LBP algorithm [101]	Simple to implement	Not robust
Faster R-CNN algorithm [103]	Very high precision	No such demerits for this algorithm
