A facial recognition pipeline with a supporting Flask API for implementing face ID locks in applications.

Objective: Implement face recognition using DeepFace with MTCNN and RetinaFace as detectors.

Dependencies: Requires OpenCV, DeepFace, and associated libraries.

Execution:

• Preprocessing: Prepare video and image inputs for processing (extracting sutable frames from video before converting to embeddings)
• Face Detection: Use MTCNN and RetinaFace for detecting faces.
• Embedding Extraction: Use the ArcFace model to generate face embeddings.

Output: Generates face embeddings and provides a cosine similarity score.

Purpose: Convert the Colab notebook pipeline into a RESTful Flask API for facial recognition applications.

Endpoints:

• /extract_embeddings_from_video: Extracts face embeddings from a video file.
• /extract_embeddings_from_image: Extracts face embeddings from an image file.
• /compare_embeddings: Compares two sets of embeddings and returns a similarity score.

Usage: Accepts video/image inputs, extracts embeddings, and calculates similarity scores.

1. Run the Flask API:

   python main.py
