Installation

1. Install libjxl on your computer. cjxl and djxl needs to be available on your path.
2. Install the dependencies with pip install -r requirements.txt

Primary Data Generation

The API of the script can be found using python src/generate_primary_data.py -h. The script follows these steps :

1. Load a raw or lossless image (e.g. PNG)
2. Resize the image (if necessary) and keep the aspect ratio
3. Save the image as JPEG XL (JXL) according to a quality factor
4. Convert the JXL to a lossless format (PNG)
5. Detect the objects in the saved JXL with YOLOv5
6. Get the inference speed, the predicted classes, the confidence (%) and the actual classes
7. Save the results in a JSON file

Notes

The script is meant to work with the People Overhead dataset. To use another dataset, dataset_utils.py should be updated to retrieve the proper actual classes.

Accuracy Visualization

The following script will produce a graphic of the predictions accuracy according to the height and the quality factor. The API of the script can be found using python src/visualize_accuracy.py -h.

What could be improved

• Log and handle errors
• Automated tests
