Crowd Counting Code Framework (C^3-Framework)

Python 3 dev version!

An open-source PyTorch code for crowd counting

Note: Due to personal reasons, the code will not continue to be maintained. I suggest you use NWPU-Crowd-Sample-Code or use other excellent code in Awesome-Crowd-Counting.

Goal

The purpose of this code is an efficient, flexible framework for supervised crowd counting. At the same time, we provide the performances of some basic networks and classic algorithms on the mainstream datasets.

Features

  • Convenient development kit. It is a convenient dev kit on the six maintream datasets.
  • Solid baselines. It provides some baselines of some classic pre-trained models, such as AlexNet, VGG, ResNet and so on. Base on it, you can easily compare your proposed models' effects with them.
  • Powerful log. It does not only record the loss, visualization in Tensorboard, but also save the current code package (including parameters settings). The saved code package can be directly ran to reproduce the experiments at any time. You won't be bothered by forgetting the confused parameters.

Performance

Due to limited spare time and the number of GPUs, I do not plan to conduct some experiments (named as "TBD"). If you are interested in the project, you are welcomed to submit your own experimental parameters and results. GCC(rd,cc,cl) stand for GCC dataset using random/cross-camera/cross-location/ splitting, respectively.

Getting Started

Preparation

  • Prerequisites

    • Python 3.x
    • Pytorch 1.0 (some networks only support 0.4): http://pytorch.org .
    • other libs in requirements.txt, run pip install -r requirements.txt.

  • Installation

    • Clone this repo: 
      git clone https://github.com/gjy3035/C-3-Framework.git

  • Data Preparation

    • In ./datasets/XXX/readme.md, download our processed dataset or run the prepare_XXX.m/.py to generate the desity maps. If you want to directly download all processeed data (including Shanghai Tech, UCF-QNRF, UCF_CC_50 and WorldExpo'10), please visit the link.
    • Place the processed data to ../ProcessedData.

  • Pretrained Model

    • Some Counting Networks (such as VGG, CSRNet and so on) adopt the pre-trained models on ImageNet. You can download them from TorchVision
    • Place the processed model to ~/.cache/torch/checkpoints/ (only for linux OS).

Training

  • set the parameters in config.py and ./datasets/XXX/setting.py (if you want to reproduce our results, you are recommonded to use our parameters in ./results_reports).
  • run python train.py.
  • run tensorboard --logdir=exp --port=6006.

Testing

We only provide an example to test the model on the test set. You may need to modify it to test your own models.

Pretrained Models on GCC

Considering the large-scale GCC, we provide the pretrained models on GCC using random splitting to save the researcher's training time. You can download them from this link. Unfortunately, we've lost the MCNN model trained on GCC, and we will re-train and release it ASAP.

Tips

In this code, the validation is directly on the test set. Strictly speaking, it should be evaluated on the val set (randomly selected from the training set, which is adopted in the paper). Here, for a comparable reproduction (namely fixed splitting sets), this code directly adopts the test set for validation, which causes that the results of this code are better than that of our paper. If you use this repo for academic research, you need to select 10% training data (or other value) as validation set.
