How Face Recognition Works

Face Detection

Facial recognition involves four crucial steps. The first step is face detection, where the system identifies and locates human faces within an image or video.

Alignment

Following face detection, the next step is alignment. This process normalizes the face’s position, ensuring consistency for accurate comparison.

Feature Extraction

Once aligned, the system performs feature extraction. It analyzes unique facial features like eyes, nose, and mouth to create a digital representation.

Matching Against a Face Database

The final step is matching against a face database. The system compares the extracted features with stored data to identify or verify the individual.

Geometric vs. Photometric Approaches

In facial recognition algorithms, two main approaches are used: geometric and photometric. Geometric methods focus on the spatial relationships between facial features, while photometric methods consider light variations for identification.

Transition from Traditional to Modern Methods

Historically, facial recognition relied on traditional techniques like eigenfaces, which analyzed principal components of faces for recognition. However, with advancements in technology, modern approaches leverage sophisticated machine learning algorithms for more accurate and efficient identification processes.
