Exploiting a Joint Embedding Space for Generalized Zero-Shot Semantic Segmentation
This is an official implementation of the paper "Exploiting a Joint Embedding Space for Generalized Zero-Shot Semantic Segmentation", accepted to ICCV2021.
For more information, please checkout the project site [website] and the paper [arXiv].
Pre-requisites
This repository uses the following libraries:
- Python (3.6)
- Pytorch (1.8.1)
Getting Started
Datasets
VOC
The structure of data path should be organized as follows:
/dataset/PASCALVOC/VOCdevkit/VOC2012/ % Pascal VOC datasets root
/dataset/PASCALVOC/VOCdevkit/VOC2012/JPEGImages/ % Pascal VOC images
/dataset/PASCALVOC/VOCdevkit/VOC2012/SegmentationClass/ % Pascal VOC segmentation maps
/dataset/PASCALVOC/VOCdevkit/VOC2012/ImageSets/Segmentation/ % Pascal VOC splitsCONTEXT
The structure of data path should be organized as follows:
/dataset/context/ % Pascal CONTEXT dataset root
/dataset/context/59_labels.pth % Pascal CONTEXT segmentation maps
/dataset/context/pascal_context_train.txt % Pascal CONTEXT splits
/dataset/context/pascal_context_val.txt % Pascal CONTEXT splits
/dataset/PASCALVOC/VOCdevkit/VOC2012/JPEGImages/ % Pascal VOC imagesTraining
We use DeepLabV3+ with ResNet-101 as our visual encoder. Following ZS3Net, ResNet-101 is initialized with the pre-trained weights for ImageNet classification, where training samples of seen classes are used only. (weights here)
VOC
