Read.Me

• 'line.py' and 'spot.py' contains code to generate adversarial samples with HLine, VLine and Spot respectively.

Dataset

• Download the dataset from this link or link.
• Put the dataset inside the 'images/Segments_Sorted/' directory.

Train LPR model

• run 'ALPR.ipynb'
• Configure 'data_path', and 'save_path' as necessary.

To run the project

• run 'main.py'
• Configure 'mode', 'model_path', 'op_path, and 'output_path' as necessary.
• The 'model_path' must be directed to the model intended to use.

To test the dataset on model

• run 'testing.py'

Adversarial Training

• run 'AdversarialTraining.ipynb'
• Configure 'save_path' as necessary.

To generate heatmap

• run 'heatmap.py'
• Configure 'model_path' and 'output_path' as necessary.

To create gif

• run 'gif_creation.py'
• Consifure 'output_path'
• Copy and paste code below at appropriate location in spot.py or line.py of which gif you want to create

pert_img = create_spot(img.copy(), center_i, radius, rgb)
pert_image = numpy_PIL_tensor(pert_img)
#Saving the perturbed image
output_path = 'outputs/gif3/'
output_file_name = f"{radius}-{center_i}.png"
os.makedirs(output_path, exist_ok=True)
pert_image = pert_image.view(3, 160, 105)
save_image(pert_image, output_path + output_file_name)

• Use the generated image to create gif from here.
