ANPR-GIA

Set up

1. Create a virtual environment

conda env create -f environment.yml
conda activate yolo

2. Install pytorch
   For macOS:
   conda install pytorch::pytorch torchvision -c pytorch
   For Windows or Linux, if you have Nvidia GPU:
   conda install pytorch torchvision pytorch-cuda=11.8 -c pytorch -c nvidia
   For Linux, if you have AMD GPU:
   pip install torch torchvision --index-url https://download.pytorch.org/whl/rocm6.0
   If not, install for CPU:
   conda install pytorch torchvision cpuonly -c pytorch

Repo structure

• pipeline.py: contains the full and clean implementation of our pipeline to detect and recognize license plates.
• notebooks/: folder with notebooks of the process that lead to the final code.
  • comparisonOCR.ipynb: script with metrics comparing Tesseract, EasyOCR and PaddleOCR for recognition.
  • comparisonYoloMathMorph.ipynb: script with examples and metrics of the two detection models we used.
