Pytorch Implementation for FBL

[CVPR-2023] Federated Incremental Semantic Segmentation

This is the official implementation code of our paper "Federated Incremental Semantic Segmentation" accepted by CVPR-2023.

You can also find the arXiv version with supplementary material at here.

This repository contains all of our source code. We sincerely thank the help of other repositories: Cermelli et al.'s repository, Douillard et al.'s repository, and Zhang et al.'s repository.

Brief Introduction

overview

Requirements

Recommend: You can directly use our encapsulated files (FCIL.zip) to create an environment. The steps are as follows:

1) unzip FCIL.zip
2) conda create -n FCIL --clone ./FCIL
3) pip uninstall matplotlib
4) pip install matplotlib==3.3.4

Dataset

Two scripts are available to download ADE20k and Pascal-VOC 2012, please see in the data folder.

How to perform training

The default is to use a pretraining for the backbone used, that is searched in the pretrained folder of the project. We used the pretrained model released by the authors of In-place ABN, that can be found here: link(place the downloaded "resnet101_iabn_sync.pth.tar" in the "pretrained" folder of the project).

We also provided 4 trained base models corresponding to the 4 settings used in our paper (i.e., VOC 4-4/8-2/10-1, ade 100-10)(place the downloaded base models in the "checkpoints/seed_2023-ov" folder of the project). Your future development can be directly based on our trained base models, just add "--base_weights" option to your own shell scripts.

Example commands

nohup bash scripts/voc/ours_4-4_overlap.sh >logs/voc/ours_4-4_overlap.log 2>&1 &
nohup bash scripts/ade/ours_100-10_overlap.sh >logs/ade/ours_100-10_overlap.log 2>&1 &
