How do face recognition algorithms detect human faces?


The face recognition process is performed in two stages. In first stage, the facial features of a person having unique identity are recorded. Where as in second stage, captured features are classified and matched with available database.

Facial recognition algorithm capture features such as size, position, shape and color of parts of human face which includes eyes, nose, cheekbones and jaw. This algorithm uses two techniques.

The first one is called geometric technique in which distinguish features are recorded. The second technique is called photometric technique in which every image is converted into values for comparison.

The measurement system uses 3 dimensional feature which captures facial textures from different angles with the help of sensors. Facial recognition system software uses multiple technique. It uses Skin texture analysis to cover the skin part of human. Thermal imaging is also used to capture energy level in low light conditions.
