How can we detect human face?

The temporal lobe of the brain is partly responsible for our ability to recognize faces. Some neurons in the temporal lobe respond to particular features of faces. Some people who suffer damage to the temporal lobe lose their ability to recognize and identify familiar faces.

One method of processing images is via face detection . Face detection is a branch of image processing that uses machine learning to detect faces in images. A Haar Cascade is an object detection method used to locate an object of interest in images.

Detect Faces in a remote image For your convenience, the Vision API can perform feature detection directly on an image file located in Google Cloud Storage or on the Web without the need to send the contents of the image file in the body of your request.

Face detection algorithms typically start by searching for human eyes — one of the easiest features to detect. The algorithm might then attempt to detect eyebrows, the mouth, nose, nostrils and the iris.
