Face detection and face recognition are two prevalent computer vision techniques that use deep learning to identify and categorize human face features.

Here is a quick explanation of how each function:

Face detection algorithms are made to find and extract faces from pictures and movies.

A face detection algorithm typically uses an input picture or video to generate a collection of bounding boxes that pinpoints where faces are located in the image and video.

The system will then remove certain areas from the image and send them for additional processing to a face recognition algorithm.

Since deep learning algorithms are so good at spotting intricate patterns and characteristics in images, they are frequently utilized in face identification applications.

Due to their suitability for image processing applications, convolutional neural networks (CNNs) are a prominent architecture utilized in face detection models.

Face Recognition: Algorithms for face recognition are created to recognize and categorize faces based on their distinctive traits.

A face recognition algorithm typically takes an input image or video and extracts a collection of attributes specific to that face, such as the separation between the eyes or the curve of the nose etc.

The program will next attempt to identify the individual in the picture or video by comparing those attributes to a database of trained faces.

As deep learning algorithms can extract highly discriminative characteristics from photographs in difficult circumstances such as changes in lighting, position, and expression, they are frequently utilized in face recognition applications.

Since they are excellent at image processing tasks, convolutional neural networks (CNNs) are a frequent architecture used in face recognition models.

Many well-known deep-learning models for face detection and identification are listed below:
