Face Recognition in a Directory

Overview

This project provides a Python script to perform face recognition on all images within a specified directory. Using OpenCV, the YuNet face detection model, and pre-trained face recognition models, the script detects and recognizes faces in each image. Recognized faces are logged, and matching images can be copied to a specified directory.

For those moments when you have an entire folder of vacation photos and need to find out if your friend’s face appears in every single one of them—this tool’s got your back 😉.

Features

  • Detect and recognize faces in a directory of images using the YuNet face detection model.
  • Logs recognized faces with accuracy scores to a text file.
  • Copy images with recognized faces to a specified directory.
  • Progress tracking with a visual progress bar using tqdm.

Requirements

opencv-python
numpy
tqdm

Installation

  1. Clone the repository:

    git clone https://github.com/Andrei-Iosifescu123/batch-face-recognition.git
cd batch-face-recognition

  2. Install the required packages:

    pip3 install -r requirements.txt

Usage

Arguments

  • --target or -t: Path to the target image containing the face to match against.
  • --query_dir or -q: Directory containing images to search for faces.
  • --model or -m: Path to the face recognition model (default: face_recognition_sface_2021dec.onnx).
  • --backend_target or -bt: Choose the backend-target combination to run the demo. Options include:
    0: OpenCV + CPU (default)
    1: CUDA + GPU
    2: CUDA + GPU (FP16)
    3: TIM-VX + NPU
    4: CANN + NPU
  • --dis_type: Distance type for face matching (0: cosine, 1: norm_l1; default: 0).
  • --save or -s: Directory to copy images with recognized faces. If not provided, images won’t be copied.
  • --threshold or -th: Accuracy threshold for recognizing faces (default: 0.6).
  • --logfile or -l: Path to the log file to record recognized faces. If not provided, no log is created.

Example

The following command will recognize all faces in the /media/hdd/family_photos directory matching the face in the image Emily.jpg, without saving matching images or outputting to a logfile:

python3 main.py --target Emily.jpg --query_dir /media/hdd/family_photos
