CPPE - 5 (Medical Personal Protective Equipment) is a new challenging dataset with the goal to allow the study of subordinate categorization of medical personal protective equipments, which is not possible with other popular data sets that focus on broad level categories.

Accompanying paper: CPPE - 5: Medical Personal Protective Equipment Dataset

by Rishit Dagli and Ali Mustufa Shaikh.

Some features of this dataset are:

• high quality images and annotations (~4.6 bounding boxes per image)
• real-life images unlike any current such dataset
• majority of non-iconic images (allowing easy deployment to real-world environments)
• >15 pre-trained models in the model zoo availaible to directly use (also for mobile and edge devices)

• 06/01/2022 - Many thanks to @mariosasko for creating a Hugging Face Datasets loader.
• 05/01/2022 - This paper got featured on Google Research TRC's publication section
• 20/12/2021 - First public release of the CPPE - 5 dataset on arXiv

We strongly recommend you use either the downlaoder script or the Python package to download the dataset however you could also download and extract it manually.

The easiest way to download the dataset is to use the downloader script:

git clone https://github.com/Rishit-dagli/CPPE-Dataset.git
cd CPPE-Dataset
bash tools/download.sh

You can also use the Python package to get the dataset:

pip install cppe5

import cppe5
cppe5.download_data()

We provide PyTorch and TensorFlow data loaders in this repository, the dataset can also be loaded from Hugging Face Datasets. To use the data loaders in this repository you would need to install the Python package first:

pip install cppe5

Install the datasets library first:

pip install datasets

from datasets import load_dataset

dataset = load_dataset("cppe-5")

A ready to run Google Colab example can be found at notebooks/pytorch_loader.ipynb.

import cppe5
from cppe5.torch import data_loader
import os

cppe5.download_data()
os.chdir("..")
data_loader = cppe5.torch.data_loader() # torch.utils.data.DataLoader

# Fetch all images and annotations
device = torch.device("cuda") if torch.cuda.is_available() else torch.device("cpu")

# DataLoader is iterable over Dataset
for imgs, annotations in data_loader:
    imgs = list(img.to(device) for img in imgs)
    annotations = [{k: v.to(device) for k, v in t.items()} for t in annotations]

A ready to run Google Colab example can be found at notebooks/tensorflow_loader.ipynb.

import cppe5
from cppe5.tensorflow import data_loader

cppe5.download_tfrecords()
os.chdir("..")

dataset = cppe5.tensorflow.data_loader() # tf.data.Dataset
iter(dataset).next()

The dataset contains the following labels:

More information about the pre-trained models (like modlel complexity or FPS benchmark) could be found in MODEL_ZOO.md and LITE_MODEL_ZOO.md includes models ready for deployment on mobile and edge devices.

This section contains the baseline models that are trained on the CPPE-5 dataset . More information about how these are trained could be found in the original paper and the config files.

This section contains the SoTA models that are trained on the CPPE-5 dataset . More information about how these are trained could be found in the original paper and the config files.

We also include the following tools in this repository to make working with the dataset a lot easier:

• Download data
• Download TF Record files
• Convert PNG images in dataset to JPG Images
• Converting Pascal VOC to COCO format
• Update dataset to use relative paths

More information about each tool can be found in the tools/README.md file.

We also present some tutorials on how to use the dataset in this repository as Colab notebooks:

• pytorch_loader.ipynb

In this notebook we will load the CPPE - 5 dataset in PyTorch and also see a quick example of fine-tuning the Faster RCNN model with torchvision on this dataset.

• tensorflow_loader.ipynb

In this notebook we will load the CPPE - 5 dataset through TF Record files in TensorFlow.

• visualize.ipynb

In this notebook, we will visualize the CPPE-5 dataset, which could be really helpful to see some sample images and annotations from the dataset.
