As per Biometric dealers in Hyderabad facial recognition systems use computer algorithms to identify and verify the identity of an individual by analysing and comparing their facial features with a database of known faces.
Here is a general overview of how a face recognition system works:
- Face detection: The system uses an image sensor, such as a camera, to capture an image of a person's face. The image is then analyzed to detect the location of the face in the image.
- Feature extraction: Once the system has detected a face, it extracts specific features of the face, such as the distance between the eyes, the shape of the nose, the depth of the eye sockets, etc. These features are then converted into a mathematical representation, usually as a series of numbers, which can be stored in a database.
- Face matching: The system then compares the extracted features of the person's face with the features of faces in the database. It uses sophisticated algorithms to identify similarities and differences between the features and assigns a score to the degree of similarity between the two sets of features.
- Identification/Verification: Based on the score, the system determines whether the person's face matches any of the faces in the database. If it does, the system identifies the person. If it does not, the system rejects the match.
As per Biometric dealers in Hyderabad there are different types of face recognition systems, including 2D, 3D, and thermal imaging. The technology used and the algorithms employed can vary between different systems, but the basic process remains the same.
