A Pytorch implementation of DeepCrack and RoadNet projects.
Please download the corresponding dataset and prepare it by following the guidance.
We provide an user-friendly configuring method via Conda system, and you can create a new Conda environment using the command:
conda env create -f environment.yml
We follow the Median Frequency Balancing method, using the command:
python3 ./tools/calculate_weights.py --data_path <path_to_segmentation>
Before the training, please download the dataset and copy it into the folder datasets.

- Metrics (appeared in our papers):
| Metric | Description | Usage |
|---|---|---|
| P | Precision, TP/(TP+FP) |
segmentation |
| R | Recall, TP/(TP+FN) |
segmentation |
| F | F-score, 2PR/(P+R) |
segmentation |
| TPR | True Positive Rate, TP/(TP+FN) |
segmentation |
| FPR | False Positive Rate, FP/(FP+TN) |
segmentation |
| AUC | The Area Under the ROC Curve | segmentation |
| G | Global accuracy, measures the percentage of the pixels correctly predicted | segmentation |
| C | Class average accuracy, means the predictive accuracy over all classes | segmentation |
| I/U | Mean intersection over union | segmentation |
| ODS | the best F-measure on the dataset for a fixed scale | edge,centerline |
| OIS | the aggregate F-measure on the dataset for the best scale in each image | edge,centerline |
| AP | the average precision on the full recall range | edge,centerline |
Note: If you want to apply the standard non-maximum suppression (NMS) for edge/centerline thinning. Please see more details in Piotr's Structured Forest matlab toolbox or some helper functions provided in the hed/eval.
