Deep learning models and dataset for recognizing industrial smoke emissions. The videos are from the smoke labeling tool. The code in this repository assumes that Ubuntu 18.04 server is installed. If you found this dataset and the code useful, we would greatly appreciate it if you could cite our technical report below:

Yen-Chia Hsu, Ting-Hao (Kenneth) Huang, Ting-Yao Hu, Paul Dille, Sean Prendi, Ryan Hoffman, Anastasia Tsuhlares, Randy Sargent, and Illah Nourbakhsh. 2020. RISE Video Dataset: Recognizing Industrial Smoke Emissions. arXiv preprint arXiv:2005.06111.

This figure shows different types of videos (high-opacity smoke, low-opacity smoke, steam, and steam with smoke).

The following figures show how the I3D model recognizes industrial smoke. The heatmaps (red and yellow areas on top of the images) indicate where the model thinks have smoke emissions. The examples are from the testing set with different camera views, which means that the model never sees these views at the training stage. These visualizations are generated by using the Grad-CAM technique. The x-axis indicates time.

Setup this tool

Install conda. This assumes that Ubuntu is installed. A detailed documentation is here. First visit here to obtain the downloading path. The following script install conda for all users:

sudo sh -b -p /opt/miniconda3

sudo vim /etc/bash.bashrc
# Add the following lines to this file
export PATH="/opt/miniconda3/bin:$PATH"
. /opt/miniconda3/etc/profile.d/

source /etc/bash.bashrc

For Mac OS, I recommend installing conda by using Homebrew.

brew cask install miniconda
echo 'export PATH="/usr/local/Caskroom/miniconda/base/bin:$PATH"' >> ~/.bash_profile
echo '. /usr/local/Caskroom/miniconda/base/etc/profile.d/' >> ~/.bash_profile
source ~/.bash_profile

Clone this repository and set the permission.

git clone --recursive
sudo chown -R $USER deep-smoke-machine/
sudo addgroup [group_name]
sudo usermod -a -G [group_name] [user_name]
groups [user_name]
sudo chmod -R 775 deep-smoke-machine/
sudo chgrp -R [group_name] deep-smoke-machine/

For git to ignore permission changes.

# For only this repository
git config core.fileMode false

# For globally
git config --global core.fileMode false

Create conda environment and install packages. It is important to install pip first inside the newly created conda environment.

conda create -n deep-smoke-machine
conda activate deep-smoke-machine
conda install python=3.7
conda install pip
which pip # make sure this is the pip inside the deep-smoke-machine environment
sh deep-smoke-machine/back-end/

If the environment already exists and you want to remove it before installing packages, use the following:

conda env remove -n deep-smoke-machine

Update the optical_flow submodule.

cd deep-smoke-machine/back-end/www/optical_flow/
git submodule update --init --recursive
git checkout master

Install PyTorch.

conda install pytorch torchvision -c pytorch

Install system packages for OpenCV.

sudo apt update
sudo apt install -y libsm6 libxext6 libxrender-dev

Use this tool

Obtain user token from the smoke labeling tool and put the user_token.js file in the deep-smoke-machine/back-end/data/ directory. You need permissions from the system administrator to download the user token. After getting the token, get the video metadata. This will create a metadata.json file under deep-smoke-machine/back-end/data/.

python confirm

For others who wish to use the publicly released dataset (a snapshot of the smoke labeling tool on 2/24/2020), we include metadata_02242020.json file under the deep-smoke-machine/back-end/data/dataset/ folder. You need to copy, move, and rename this file to deep-smoke-machine/back-end/data/metadata.json.

cd deep-smoke-machine/back-end/data/
cp dataset/2020-02-24/metadata_02242020.json metadata.json

Split the metadata into three sets: train, validation, and test. This will create a deep-smoke-machine/back-end/data/split/ folder that contains all splits, as indicated in our technical report. The method for splitting the dataset will be explained in the next "Dataset" section.

python confirm

Download all videos in the metadata file to deep-smoke-machine/back-end/data/videos/. We provide a shell script (see to run the python script on the background using the screen command.


# Background script (on the background using the "screen" command)
sh python

Here are some tips for the screen command:

# List currently running screen names
sudo screen -ls

# Go into a screen
sudo screen -x [NAME_FROM_ABOVE_COMMAND] (e.g. sudo screen -x 33186.download_videos)
# Inside the screen, use CTRL+C to terminate the screen
# Or use CTRL+A+D to detach the screen and send it to the background

# Terminate all screens
sudo screen -X quit

# Keep looking at the screen log
tail -f screenlog.0

Process and save all videos into RGB frames (under deep-smoke-machine/back-end/data/rgb/) and optical flow frames (under deep-smoke-machine/back-end/data/flow/). Because computing optical flow takes a very long time, by default, this script will only process RGB frames. If you need the optical flow frames, change the flow_type to 1 in the script.


# Background script (on the background using the "screen" command)
sh python

Extract I3D features under deep-smoke-machine/back-end/data/i3d_features_rgb/ and deep-smoke-machine/back-end/data/i3d_features_flow/. Notice that you need to process the optical flow frames in the previous step to run the i3d-flow model.

python [method] [optional_model_path]

# Extract features from pretrained i3d
python i3d-rgb
python i3d-flow

# Extract features from a saved i3d model
python i3d-rgb ../data/saved_i3d/ecf7308-i3d-rgb/model/
python i3d-flow ../data/saved_i3d/af00751-i3d-flow/model/

# Background script (on the background using the "screen" command)
sh python i3d-rgb
sh python i3d-flow

Train the model with cross-validation on all dataset splits, using different hyper-parameters. The model will be trained on the training set and validated on the validation set. Pretrained weights are obtained from the pytorch-i3d repository. By default, the information of the trained I3D model will be placed in the deep-smoke-machine/back-end/data/saved_i3d/ folder. For the description of the models, please refer to our technical report. Note that by default the PyTorch DistributedDataParallel GPU parallel computing is enabled (see

python [method] [optional_model_path]

# Use I3D features + SVM
python svm-rgb-cv-1

# Use Two-Stream Inflated 3D ConvNet
python i3d-rgb-cv-1

# Background script (on the background using the "screen" command)
sh python i3d-rgb-cv-1

Test the performance of a model on the test set. This step will also generate summary videos for each cell in the confusion matrix (true positive, true negative, false positive, and false negative).

python [method] [model_path]

# Use I3D features + SVM
python svm-rgb-cv-1 ../data/saved_svm/445cc62-svm-rgb/model/model.pkl

# Use Two-Stream Inflated 3D ConvNet
python i3d-rgb-cv-1 ../data/saved_i3d/ecf7308-i3d-rgb/model/

# Background script (on the background using the "screen" command)
sh python i3d-rgb-cv-1 ../data/saved_i3d/ecf7308-i3d-rgb/model/

Run Grad-CAM to visualize the areas in the videos that the model is looking at.

python i3d-rgb [model_path]

# Background script (on the background using the "screen" command)
sh python i3d-rgb [model_path]

After model training and testing, the folder structure will look like the following:

└── saved_i3d                            # this corresponds to deep-smoke-machine/back-end/data/saved_i3d/
    └── 549f8df-i3d-rgb-s1               # the name of the model, s1 means split 1
        ├── cam                          # the visualization using Grad-CAM
        ├── log                          # the log when training models
        ├── metadata                     # the metadata of the dataset split
        ├── model                        # the saved models
        ├── run                          # the saved information for TensorBoard
        └── viz                          # the sampled videos for each cell in the confusion matrix

If you want to see the training and testing results on TensorBoard, run the following and go to the stated URL in your browser.

cd deep-smoke-machine/back-end/data/
tensorboard --logdir=saved_i3d

Recommended training strategy:

  1. Set an initial learning rate (e.g., 0.1)
  2. Keep this learning rate and train the model until the training error decreases too slow (or fluctuate) or until the validation error increases (a sign of overfitting)
  3. Decrease the learning rate (e.g., by a factor of 10)
  4. Load the best model weight from the ones that were trained using the previous learning rate
  5. Repeat step 2, 3, and 4 until convergence

Code infrastructure

This section explains the code infrastructure related to the I3D model training and testing in the deep-smoke-machine/back-end/www/ folder. Later in this section, I will describe how to build your own model and integrate it with the current pipeline. This code assumes that you are familiar with the PyTorch deep learning framework. If you do not know PyTorch, I recommend checking their tutorial page first.

If you want to develop your own model, here are the steps that I recommend.

  1. Play with the script to understand the input and output dimensions.
  2. Create your own model and place it in the deep-smoke-machine/back-end/www/model/ folder. You can take a look at other models to get an idea about how to write the code.
  3. Import your model to the script, then run the script to debug your model.
  4. If you need a specific data augmentation pipeline, edit the get_transform function in the file. Depending on your needs, you may also need to edit the and files.
  5. Copy the file, import your model, and modify the code to suit your needs. Make sure that you import your customized learner class in the and files.

Pretrained models

We are working on a pipeline for recognizing smoke emissions using existing camera data, and we will release our best pre-trained models here.


We include our publicly released dataset (a snapshot of the smoke labeling tool on 2/24/2020) metadata_02242020.json file under the deep-smoke-machine/back-end/data/dataset/ folder. The JSON file contains an array, with each element in the array representing the metadata for a video. Each element is a dictionary with keys and values, explained below:

Note that the url_root and url_part point to videos with 180 by 180 resolutions. We also provide a higher resolution (320 by 320) version of the videos. Replace the "/180/" with "/320/" in the url_root, and also replace the "-180-180-" with "-320-320-" in the url_part. For example, see the following:

Each video is reviewed by at least two citizen science volunteers (or one researcher who received the smoke reading training). Our technical report describes the details of the labeling and quality control mechanism. The state of the label (label_state and label_state_admin) in the metadata_02242020.json is briefly explained below.

After running the script, the "label_state" and "label_state_admin" keys in the dictionary will be aggregated into the final label, represented by the new "label" key (see the JSON files in the generated deep-smoke-machine/back-end/data/split/ folder). Positive (value 1) and negative (value 0) labels mean if the video clip has smoke emissions or not, respectively.

Also, the dataset will be divided into several splits, based on camera views or dates. The file names (without ".json" file extension) are listed below. The Split S0, S1, S2, S3, S4, and S5 correspond to the ones indicated in the technical report.

Split Train Validate Test
S0 metadata_train_split_0_by_camera metadata_validation_split_0_by_camera metadata_test_split_0_by_camera
S1 metadata_train_split_1_by_camera metadata_validation_split_1_by_camera metadata_test_split_1_by_camera
S2 metadata_train_split_2_by_camera metadata_validation_split_2_by_camera metadata_test_split_2_by_camera
S3 metadata_train_split_by_date metadata_validation_split_by_date metadata_test_split_by_date
S4 metadata_train_split_3_by_camera metadata_validation_split_3_by_camera metadata_test_split_3_by_camera
S5 metadata_train_split_4_by_camera metadata_validation_split_4_by_camera metadata_test_split_4_by_camera

The following table shows the content in each split, except S3. The splitting strategy is that each view will be present in the testing set at least once. Also, the camera views that monitor different industrial facilities (view 1-0, 2-0, 2-1, and 2-2) are always on the testing set. Examples of the camera views will be provided later in this section.

0-0 Train Train Test Train Train
0-1 Test Train Train Train Train
0-2 Train Test Train Train Train
0-3 Train Train Validate Train Test
0-4 Validate Train Train Test Validate

0-14 Train Test Train Train Train
1-0 Test Test Test Test Test
2-0 Test Test Test Test Test
2-1 Test Test Test Test Test
2-2 Test Test Test Test Test

The following shows the split of S3 by time sequence, where the farthermost 18 days are used for training, the middle 2 days are used for validation, and the nearest 10 days are used for testing. You can find our camera data by date on our air pollution monitoring network.

The dataset contains 12,567 clips with 19 distinct views from cameras on three sites that monitored three different industrial facilities. The clips are from 30 days that spans four seasons in two years in the daytime. The following provides examples and the distribution of labels for each camera view, with the format [camera_id]-[view_id]:
