Build-a-convolutional-neural-network-with-Tensorflow-and-Keras

This is a tutorial for building a CNN with tensorflow and keras. The model will be used for plate recognition. The model is then converted to used by OpenCV dnn in a C# application.

Prerequisite

• Packages: tensorflow, keras, scikit-learn, matplotlib
• Project structure

• Link for the train data https://drive.google.com/open?id=1ls1J-F21J-Vzi9ZcgUL-_4QPhfoIdzBL

Implementation

• Train the model

python train.py --dataset train_data --model model.model --label-bin bin --plot plot

• Convert the model to tensorflow model

python Convert_keras_to_tf.py --keras_model model.model --tf_model tf_model.pb

• Test the tensorflow model

python Prediction_tf_pb.py

Result

• Accuracy: 99,9% after 20 epochs
• Processing time: 3ms/1 image
