Scene-Aware Label Graph Learning for Multi-Label Image Classification

Introduction

This is an official PyTorch implementation of Scene-Aware Label Graph Learning for Multi-Label Image Classification, ICCV 2023. [paper]

Data Preparation

1. Download dataset and organize them as follow:

|datasets
|---- MSCOCO
|-------- annotations
|-------- train2014
|-------- val2014
|---- NUS-WIDE
|-------- Flickr
|-------- Groundtruth
|-------- ImageList
|-------- NUS_WID_Tags
|-------- Concepts81.txt
|---- VOC2007
|-------- Annotations
|-------- ImageSets
|-------- JPEGImages
|-------- SegmentationClass
|-------- SegmentationObject

2. Preprocess using following commands:

python scripts/mscoco.py
python scripts/nuswide.py
python scripts/voc2007.py
python embedding.py --data [mscoco, nuswide, voc2007]

Requirements

torch >= 1.9.0
torchvision >= 0.10.0

Evaluation

Pre-trained weights can be found in google drive. Download and put them in the experiments folder, then one can use following commands to reproduce results reported in paper.

python evaluate.py --exp-dir experiments/salgl_resnet101_mscoco/exp3     # Microsoft COCO (448 x 448)
python evaluate.py --exp-dir experiments/salgl_resnet101_mscoco/exp6     # Microsoft COCO (576 x 576)
python evaluate.py --exp-dir experiments/salgl_resnet101_nuswide/exp2    # NUS-WIDE
python evaluate.py --exp-dir experiments/salgl_vit_large_patch16_224_mscoco/exp1     # Pascal VOC 2007

Visualization

To visualize the word cloud and the label co-occurrence probability heatmap of different scene categories, please first download coco experiments (salgl_resnet101_mscoco) and then run following commands:

python labelcloud.py --exp-dir experiments/salgl_resnet101_mscoco/exp3
python heatmap.py --exp-dir experiments/salgl_resnet101_mscoco/exp3
