This repository contains the StreetHazards dataset and some code for the paper A Benchmark for Anomaly Segmentation.
Download the StreetHazards anomaly segmentation dataset here.
The optional StreetHazards training set is available here. Also, the BDD-Anomaly dataset is sourced from the BDD100K dataset. Code for the multi-label out-of-distribution detection experiments is available in this repository.

# Place the above download in semantic-segmentation-pytorch/data/
# Train pspnet or another model on our dataset
python3 train.py
# To evaluate the model on out of distribution test set
python3 eval_ood.py --DATASET.list_val ./data/test.odgt
To evaluate the model performance using a CRF with our code please install
pip install pydensecrf
The source package is from https://github.com/lucasb-eyer/pydensecrf
Within the create_dataset.py file we provide a function that converts the BDD100K labels into the labels we used for our experiments. We have commented out the section that creates the odgt files that we used for BDD100K. Uncommenting and running will generate the appropriate labels used for training and testing. The remaining procedure is the same as described above.
