# Zero-shot Object Counting with Good Exemplars
## News🚀
* **2024.09.27**: Our code is released.
* **2024.09.26**: Our inference code has been updated, and the code for selecting exemplars and the training code will be coming soon.
* **2024.07.02**: VA-Count is accepted by ECCV2024.
## Overview 
Overview of the proposed method. The proposed method focuses on two main elements: the Exemplar Enhancement Module (EEM) for improving exemplar quality through a patch selection integrated with Grounding DINO, and the Noise Suppression Module (NSM) that distinguishes between positive and negative class samples using density maps. It employs a Contrastive Loss function to refine the precision in identifying target class objects from others in an image.
## Environment
```
pip install torch==1.10.0+cu111 torchvision==0.11.0+cu111 torchaudio==0.10.0 -f https://download.pytorch.org/whl/torch_stable.html
pip install timm==0.3.2
pip install numpy
pip install matplotlib tqdm 
pip install tensorboard
pip install scipy
pip install imgaug
pip install opencv-python
pip3 install hub
```

## Inference
+  For inference, you can download the model from [Baidu-Disk](https://pan.baidu.com/s/11sbdDYLDfTOIPx5pZvBpmw?pwd=paeh), passward:paeh
```
python FSC_test.py --output_dir ./data/out/results_base --resume ./data/checkpoint_FSC.pth
```
## Single and Multiple Object Classifier Training
```
python datasetmake.py
python biclassify.py
```
+  You can also directly download the model from [Baidu-Disk](https://pan.baidu.com/s/1fOF0giI3yQpvGTiNFUI7cQ?pwd=psum), passward:psum Save it in ./data/out/classify/
## Generate exemplars
```
python grounding_pos.py --root_path ./data/FSC147/
python grounding_neg.py --root_path ./data/FSC147/
```

## Train

```
CUDA_VISIBLE_DEVICES=0 python FSC_pretrain.py \
    --epochs 500 \
    --warmup_epochs 10 \
    --blr 1.5e-4 --weight_decay 0.05
```
+  You can also directly download the pre-train model from [Baidu-Disk](https://pan.baidu.com/s/1_-w_9I4bPA66pMZkHTrdrg?pwd=xynw), passward:xynw Save it in ./data/ 
```
CUDA_VISIBLE_DEVICES=0 python FSC_train.py --epochs 1000 --batch_size 8 --lr 1e-5 --output_dir ./data/out/
