This repository contains the code of the Real-Time Anomaly Segmentation for Road Scenes project of the Advanced Machine Learning course 23/24 - Politecnico di Torino
This repository was built on the following repository base: erfnet_pytorch.
A brief overview of the project is available at s326619_s330509_project4.pdf.
Example of Anomaly scores calculated by an ERFNet model using the MaxLogit inference method.
For instructions, please refer to the README in each folder:
- train contains tools for training the networks for semantic segmentation.
- eval contains tools for evaluating/visualizing the networks' output and performing anomaly segmentation.
- imagenet contains scripts and model for pretraining ERFNet's encoder in Imagenet.
- trained_models contains some trained models used in the papers (almost all the models are available in the Releases section).
- The Cityscapes dataset: Download the "leftImg8bit" for the RGB images and the "gtFine" for the labels. Please note that for training you should use the "_labelTrainIds" and not the "_labelIds", you can download the cityscapes scripts and use the conversor to generate trainIds from labelIds
- For testing the anomaly segmentation models: All testing images are provided here.
The repo provides the following pre-trained networks that can be used to perform anomaly segmentation:
- Erfnet trained on 19 classes of the Cityscapes dataset using a Cross-Entropy loss, Logit Norm + Cross Entropy, Logit Norm + Focal Loss, IsoMax+ + Cross Entropy and IsoMax+ + Focal Loss
- BiSeNetV1 trained on 20 classes (19 + void class) of the Cityscapes dataset
- Enet trained on 20 classes (19 + void class) of the Cityscapes dataset
The AML_Project.ipynb can be opened on Colab to run all the evaluation commands.
