Dataset download

Images can be downloaded from here: https://drive.google.com/file/d/1ymDYrGs9DSRicfZbSCDiOu0ikGDh5k6S/view?usp=sharing

Precomputed density maps can be found here: https://archive.org/details/FSC147-GT

Place the unzipped image directory and density map directory inside the data directory.

Installation with Conda

conda create -n fscount python=3.7 -y

conda activate fscount

python -m pip install matplotlib opencv-python notebook tqdm

conda install pytorch==1.4.0 torchvision==0.5.0 cudatoolkit=10.0 -c pytorch

Quick demo

Provide the input image and also provide the bounding boxes of exemplar objects using a text file:

python demo.py --input-image orange.jpg --bbox-file orange_box_ex.txt

Use our provided interface to specify the bounding boxes for exemplar objects

python demo.py --input-image orange.jpg

Evaluation

We are providing our pretrained FamNet model, and the evaluation code can be used without the training.

Testing on validation split without adaptation

python test.py --data_path /PATH/TO/YOUR/FSC147/DATASET/ --test_split val

Testing on val split with adaptation

python test.py --data_path /PATH/TO/YOUR/FSC147/DATASET/ --test_split val --adapt

Training

python train.py --gpu 0
