Face Detection
I am not very impressedβ¦the library was not able to detect all the faces. This is a sample outputβ¦
As is clearly visible only about (4/10) faces are detected.

Although tweaking the parameters in the options seems to produce better results :

Lowering the min_detection_confidence to 0.2 resulted in a better output :

Still not all faces are detected (8/10).
