The Face Recognition system is primarily based on two types of approaches:

1. Geometric or Feature-based Approach: This method focuses on distinguishing features or landmarks on the face, such as the eyes, nose, mouth, etc. The overall configuration of these elements is used to identify the face. The distances and angles between the features are measured and compared to those in the database.

2. Photometric or Appearance-based Approach: This method uses statistical analysis on the pixel intensity of the entire or parts of the face image. Techniques like Principal Component Analysis (PCA), Linear Discriminant Analysis (LDA), or Neural Networks are used to find the variations between the faces and recognize them.

In modern systems, a hybrid approach combining both geometric and photometric methods is often used to improve accuracy and robustness.
