Usage

1. Dependencies

This code is tested on [Ubuntu18.04, tensorflow1.14, keras2.1.6, python3.6,cuda10.0,cudnn7.6].

make sure the GPU enviroment is the same as above (cuda10.0,cudnn7.6), otherwise you may have to compile the nms and utils according to https://github.com/endernewton/tf-faster-rcnn. Besides, check the keras version is keras2.1, i find there may be some mistakes if the keras version is higher. To be as simple as possible, I recommend installing the dependencies with Anaconda as follows:

1. conda create -n python36 python=3.6
2. conda activate python36
3. conda install cudatoolkit=10.0
4. conda install cudnn=7.6
5. conda install tensorflow-gpu=1.14
6. conda install keras=2.1
7. conda install opencv
8. python demo.py

2. Prerequisites

• train data (download to ./data/kaist)\ Baidu Cloud(extract code: ABCD) or KAIST website
• test data (download to ./data/kaist_test)\ Baidu Cloud(extract code: ABCD) or Google Drive
• ResNet50 pretrained model (download to ./data/models/)\ Baidu Cloud(extract code: ABCD) or Google Drive
• MBNet model(download to ./data/models/)\ Baidu Cloud(extract code: ABCD) or Google Drive

3. Demo example

3.1 Demo images

1. Check the MBNet model is available at ./data/models/resnet_e7_l224.hdf5

2. Run the script: python demo.py

3. The detection result is saved at ./data/kaist_demo/.

   3.2 Demo video

4. Check the MBNet model is available at ./data/models/resnet_e7_l224.hdf5

5. Set weight_path , test_file , lwir_test_file in demo_video.py

6. Run the script: python demo_video.py

7. The detection result videos saved at MBNet directory.

4. Evaluate model performance

1. check the MBNet model is available at ./data/models/resnet_e7_l224.hdf5 and the test data is available at ./data/kaist_test.
2. Run the script: python test.py
3. The test results are saved at ./data/result/.
4. open the KAISTdevkit-matlab-wrapper and run the demo_test.m.

5. Train your own model

1. Check the ResNet50 pretrained model is available at ./data/models/double_resnet.hdf5 and the train data is available at ./data/kaist.
2. Run the script: python train.py
3. The trained models are saved at ./output.
4. Evaluate model performance as above.

6. Comparison with other Methods

Please download the Matlab implemented comparison code [Baidu Cloud(extract code: ABCD) or Google Drive] and run the script according to the README.txt.
