AutoScale_regression

• An officical implementation of AutoScale regression-based method, you can find localization-based method from here.
• AutoScale leverages a simple yet effective Learning to Scale (L2S) module to cope with significant scale variations in both localization and regression.<br />

Datasets

• Download ShanghaiTech dataset from Baidu-Disk, passward:cjnx ; or Google-Drive
• Download UCF-QNRF Dataset from Google-Drive
• Download JHU-CROWD ++ dataset from here
• Download NWPU-CROWD dataset from Baidu-Disk, passward:9z97; or Google-Drive

Generate target

cd data<br /> Edit "distance_generate_xx.py" to change the path to your original dataset folder.<br /> python density_generate_xx.py

“xx” means the dataset name, including sh, jhu, qnrf, and nwpu.

Model

Download the pretrained model from Baidu-Disk, passward:9qfc ; or Google-Drive

Quickly test

• git clone https://github.com/dk-liang/AutoScale_regression.git<br /> cd AutoScale<br />

• Download Dataset and Model

• Generate target

• Generate images list

  Edit "make_npydata.py" to change the path to your original dataset folder.<br /> Run python make_npydata.py .

• Test <br /> python val.py --test_dataset qnrf --pre ./model/QNRF/model_best.pth --gpu_id 0<br /> python val.py --test_dataset jhu --pre ./model/JHU/model_best.pth --gpu_id 0<br /> python val.py --test_dataset nwpu --pre ./model/NWPU/model_best.pth --gpu_id 0<br /> python val.py --test_dataset ShanghaiA --pre ./model/ShanghaiA/model_best.pth --gpu_id 0<br /> python val.py --test_dataset ShanghaiB --pre ./model/ShanghaiB/model_best.pth --gpu_id 0<br /> More config information is provided in config.py
