face recognition using raspberry pi 3
How do I use face recognition on Raspberry Pi? How do you make a face recognition lock with a Raspberry Pi?

Facial recognition and biometric scanning systems also use computer vision technology to identify individuals for security purposes. The most common example of computer vision in facial recognition is for securing smartphones. More advanced uses of facial recognition and biometrics include in residential or business security systems that use unique physiological features of individuals to verify their identity. Deep learning algorithms can identify the unique patterns in a person’s fingerprints and use it to control access to high-security areas such as high-confidentiality workplaces, such as nuclear powerplants, research labs, and bank vaults.

Next, we're going to touch on using OpenCV with the Raspberry Pi's camera, giving our
Use a Raspberry Pi camera and a solenoid lock to create a door lock that
