📁 Datasets

The toolbox supports seven datasets, namely SCAMPS, UBFC-rPPG, PURE, BP4D+, UBFC-Phys, MMPD and iBVP. Please cite the corresponding papers when using these datasets. For now, we recommend training with UBFC-rPPG, PURE, iBVP or SCAMPS due to the level of synchronization and volume of the datasets. To use these datasets in a deep learning model, you should organize the files as follows.

👀 Visualization of Preprocessed Data

A python notebook for visualizing preprocessed data can be found in tools/preprocessing_viz along with an associated README. The notebook, viz_preprocessed_data.ipynb, automatically detects the preprocessed data format and then plots input image examples and waveforms.

📉 Plots of Training Losses and LR

This toolbox saves plots of training, and if applicable, validation losses automatically. Plots are saved in LOG.PATH (runs/exp by default). An example of these plots when training and validating with the UBFC-rPPG dataset and testing on the PURE dataset are shown below.

📏 Bland-Altman Plots

By default, this toolbox produces Bland-Altman plots as a part of its metrics evaluation process for both supervised and unsupervised methods. These plots are saved in the LOG.PATH (runs/exp by default). An example of these plots after training and validating with the UBFC-rPPG dataset and testing on the PURE dataset are shown below.

👀 Visualization of Neural Method Predictions

A python notebook for visualizing test-set neural method output predictions and labels can be found in tools/output_signal_viz along with an associated README. The notebook, data_out_viz.ipynb, given a .pickle output file, generated by setting TEST.OUTPUT_SAVE_DIR assists in plotting predicted PPG signals against ground-truth PPG signals.

📜 YAML File Setting

The rPPG-Toolbox uses yaml file to control all parameters for training and evaluation. You can modify the existing yaml files to meet your own training and testing requirements.

Here are some explanation of parameters:

TOOLBOX_MODE:
- train_and_test: train on the dataset and use the newly trained model to test.
- only_test: you need to set INFERENCE-MODEL_PATH, and it will use pre-trained model initialized with the MODEL_PATH to test.
TRAIN / VALID / TEST / UNSUPERVISED DATA:
- PLOT_LOSSES_AND_LR: If True, save plots of the training loss and validation loss, as well as the learning rate, to LOG.PATH (runs/exp by default). Currently, only a basic training loss and validation loss are plotted, but in the future additional losses utilized in certain trainer files (e.g., PhysFormer and BigSmall) will also be captured.
- USE_EXCLUSION_LIST: If True, utilize a provided list to exclude preprocessed videos
- SELECT_TASKS: If True, explicitly select tasks to load
- DATA_PATH: The input path of raw data
- CACHED_PATH: The output path to preprocessed data. This path also houses a directory of .csv files containing data paths to files loaded by the dataloader. This filelist (found in default at CACHED_PATH/DataFileLists). These can be viewed for users to understand which files are used in each data split (train/val/test)
- EXP_DATA_NAME If it is "", the toolbox generates a EXP_DATA_NAME based on other defined parameters. Otherwise, it uses the user-defined EXP_DATA_NAME.
- BEGIN" & "END: The portion of the dataset used for training/validation/testing. For example, if the DATASET is PURE, BEGIN is 0.0 and END is 0.8 under the TRAIN, the first 80% PURE is used for training the network. If the DATASET is PURE, BEGIN is 0.8 and END is 1.0 under the VALID, the last 20% PURE is used as the validation set. It is worth noting that validation and training sets don't have overlapping subjects.
- DATA_TYPE: How to preprocess the video data
- DATA_AUG: If present, the type of generative data augmentation applied to video data
- LABEL_TYPE: How to preprocess the label data
- USE_PSUEDO_PPG_LABEL: If True use POS generated PPG psuedo labels instead of dataset ground truth heart singal waveform
- DO_CHUNK: Whether to split the raw data into smaller chunks
- CHUNK_LENGTH: The length of each chunk (number of frames)
- DO_CROP_FACE: Whether to perform face detection
- BACKEND: Select which backend to use for face detection. Currently, the options are HC (Haar Cascade) or RF (RetinaFace). We recommend using Haar Cascade (the config default) in order to reproduce results from the NeurIPS 2023 Datasets and Benchmarks paper that corresponds to this toolbox. If you use RetinaFace, we recommend that you experiment with parameters such as LARGE_BOX_COEF and USE_MEDIAN_BOX depending on what dataset you are preprocessnig. We plan to update this README with optimal settings to use with RetinaFace in the near future.
- DYNAMIC_DETECTION: If False, face detection is only performed at the first frame and the detected box is used to crop the video for all of the subsequent frames. If True, face detection is performed at a specific frequency which is defined by DYNAMIC_DETECTION_FREQUENCY.
- DYNAMIC_DETECTION_FREQUENCY: The frequency of face detection (number of frames) if DYNAMIC_DETECTION is True
- USE_MEDIAN_FACE_BOX: If True and DYNAMIC_DETECTION is True, use the detected face boxs throughout each video to create a single, median face box per video.
- LARGE_FACE_BOX: Whether to enlarge the rectangle of the detected face region in case the detected box is not large enough for some special cases (e.g., motion videos)
- LARGE_BOX_COEF: The coefficient to scale the face box if LARGE_FACE_BOX is True.
- INFO: This is a collection of parameters based on attributes of a dataset, such as gender, motion types, and skin color, that help select videos for inclusion in training, validation, or testing. Currently, only the MMPD dataset is supported for parameter-based video inclusion. Please refer to one of the config files involving the MMPD dataset for an example of using these parameters.
- EXCLUSION_LIST: A list that specifies videos to exclude, typically based on a unique identifier to a video such as the combination of a subject ID and a task ID. This is only used if USE_EXCLUSION_LIST is set to True. Currently this parameter is only tested with the UBFC-Phys dataset. Please refer to one of the config files involving the UBFC-Phys dataset for an example of using this parameter.
- TASK_LIST: A list to specify tasks to include when loading a dataset, allowing for selective inclusion of a subset of tasks or a single task in a dataset if desired. This is only used if SELECT_TASKS is set to True. Currently this parameter is only tested with the UBFC-Phys dataset. Please refer to one of the config files involving the UBFC-Phys dataset for an example of using this parameter.
MODEL : Set used model (Deepphys, TSCAN, Physnet, EfficientPhys, BigSmall, and PhysFormer and their paramaters are supported).
UNSUPERVISED METHOD: Set used unsupervised method. Example: ["ICA", "POS", "CHROM", "GREEN", "LGI", "PBV"]
METRICS: Set used metrics. Example: ['MAE','RMSE','MAPE','Pearson','SNR','BA']
- 'BA' metric corresponds to the generation of a Bland-Altman plot to graphically compare two measurement techniques (e.g., differences between measured and ground truth heart rates versus mean of measured and ground truth heart rates). This metric saves the plot in the LOG.PATH (runs/exp by default).
INFERENCE:
- USE_SMALLER_WINDOW: If True, use an evaluation window smaller than the video length for evaluation.

📂 Adding a New Dataset

STEP 1: Create a new python file in dataset/data_loader, e.g. MyLoader.py

STEP 2: Implement the required functions, including:

def preprocess_dataset(self, config_preprocess):

@staticmethod
def read_video(video_file):

@staticmethod
def read_wave(bvp_file):

STEP 3:[Optional] Override optional functions. In principle, all functions in BaseLoader can be override, but we do not recommend you to override __len__, __get_item__,save,load.
STEP 4:Set or add configuration parameters. To set paramteters, create new yaml files in configs/ . Adding parameters requires modifying config.py, adding new parameters' definition and initial values.

🤖 Adding a New Neural Algorithms

STEP 1: Define a model in a new python file in neural_methods/model, e.g. NewModel.py.
STEP 2: Implement the corresponding training/testing routines in a file neural_methods/trainer, e.g. NewModelTrainer.py. Ensure to implement the following functions:
```
def __init__(self, config, data_loader):
```
```
def train(self, data_loader):
```
```
def valid(self, data_loader):
```
```
def test(self, data_loader)
```
```
def save_model(index)
```
STEP 3: Add logic to main.py to use the models in the following train_and_test and test functions.
STEP 4: Create new yaml files in configs/ corresponding to the new algorithm.

📈 Adding a New Unsupervised Algorithms

STEP 1: Define a algorithm in a new python file in unsupervised_methods/methods, e.g. NewMethod.py.
STEP 2: Add logic to main.py to use the models in the following unsupervised_method_inference function.
STEP 4: Create new yaml files in configs/ corresponding to the new algorithm.

📗 Weakly Supervised Training

Supervised rPPG training requires high fidelity synchronous PPG waveform labels. However not all datasets contain such high quality labels. In these cases we offer the option to train on synchronous PPG "pseudo" labels derived through a signal processing methodology. These labels are produced by using POS-generated PPG waveforms, which are then bandpass filtered around the normal heart-rate frequencies, and finally amplitude normalized using a Hilbert-signal envelope. The tight filtering and envelope normalization results in a strong periodic proxy signal, but at the cost of limited signal morphology.

📘 Motion Augmented Training

The usage of synthetic data in the training of machine learning models for medical applications is becoming a key tool that warrants further research. In addition to providing support for the fully synthetic dataset SCAMPS, we provide provide support for synthetic, motion-augmented versions of the UBFC-rPPG, PURE, SCAMPS, and UBFC-Phys datasets for further exploration toward the use of synthetic data for training rPPG models. The synthetic, motion-augmented datasets are generated using the MA-rPPG Video Toolbox, an open-source motion augmentation pipeline targeted for increasing motion diversity in rPPG videos. You can generate and utilize the aforementioned motion-augmented datasets using the steps below.

STEP 1: Follow the instructions in the README of the MA-rPPG Video Toolbox GitHub repo to generate any of the supported motion-augmented datasets. NOTE: You will have to have an original, unaugmented version of a dataset and driving video to generate a motion-augmented dataset. More information can be found here.
STEP 2: Using any config file of your choice in this toolbox, modify the DATA_AUG parameter (set to 'None' by default) to 'Motion'. Currently, only train_configs that utilize the UBFC-rPPG or PURE datasets have this parameter visible, but you can also modify other config files to add the DATA_AUG parameter below the DATA_TYPE parameter that is visible in all config files. This will enable the proper funciton for loading motion-augmented data that is in the .npy format.
STEP 3: Run the corresponding config file. Your saved model's filename will have MA appended to the corresponding data splits that are motion-augmented.

If you use the aforementioned functionality, please remember to cite the following in addition to citing the rPPG-Toolbox:

Paruchuri, A., Liu, X., Pan, Y., Patel, S., McDuff, D., & Sengupta, S. (2023). Motion Matters: Neural Motion Transfer for Better Camera Physiological Sensing. arXiv preprint arXiv:2303.12059.

Refer to this BibTeX for quick inclusion into a .bib file.

📙 Extending the Toolbox to Multi-Tasking With BigSmall

We implement BigSmall as an example to show how this toolbox may be extended to support physiological multitasking. If you use this functionality please cite the following publication:

Narayanswamy, G., Liu, Y., Yang, Y., Ma, C., Liu, X., McDuff, D., Patel, S. "BigSmall: Efficient Multi-Task Learning For Physiological Measurements" https://arxiv.org/abs/2303.11573

The BigSmall mode multi-tasks pulse (PPG regression), respiration (regression), and facial action (multilabel AU classification). The model is trained and evaluated (in this toolbox) on the AU label subset (described in the BigSmall publication) of the BP4D+ dataset, using a 3-fold cross validation method (using the same folds as in the BigSmall publication).

STEP 1: Download the BP4D+ by emailing the authors found here.
STEP 2: Modify ./configs/train_configs/BP4D_BP4D_BIGSMALL_FOLD1.yaml to train the first fold (config files also exist for the 2nd and 3rd fold).
STEP 3: Run python main.py --config_file ./configs/train_configs/BP4D_BP4D_BIGSMALL_FOLD1.yaml

📃 Using Custom Data Splits and Custom File Lists

Best practice for rPPG model evaluation involves training and validating a model on one dataset and then evaluating (testing) the performance on additional datasets (Eg. training on PURE and testing on UBFC). Data splits used for training, validation, and testing are saved as .csv filelists with the default directory path set as CACHED_PATH/DataFileLists (this are generally auto generated). In cases where users would like to define their own data splits (Eg. for intra-dataset cross validation), the following steps can be used to achieve this.

STEP 1: Collect all file paths for the data splits's input files (An example file path would be of format CACHED_PATH/PREPROCESSED_DATASET/*input*.npy, eg. 405_input9.npy). Ensure the corresponding *label*.npy files exists in the same directory as the input files.
STEP 2: Add all file paths to a .csv with column name input_files. We suggest creating a pandas dataframe and then saving this out to the csv. This .csv file is the file list for your custom data split. The file can be named anything as long as it has an .csv extension.
STEP 3: In the desired experiment config file, enter the file path of the .csv file list using keyword FILE_LIST_PATH in the DATA field of the desired train/valid/test split. The dataloader will load input and label files specified in this file path.
