    PPE detection algorithm (Facemask)

     Info
    Deployed on AWS
    This machine learning model uses computer vision to detect aggregate level of face mask use in waiting rooms within hospital waiting rooms.

    Overview

    Video-based AI that detects degree of COVID-19 facemask policy compliance. Analyzes statistical patterns at scale.

    See also separate Room Occupancy & Social Distance compliance detection module.

    Created by Providence Health Care, working with multidisciplinary teams from the University of British Columbia, including the Dept. of Computing Science & Computer Vision Lab. Our mission is to improve patient outcomes, particularly the most vulnerable in our Long-Term Care and Acute Care settings.

    Highlights

    • Our Digital Products for occupancy counting, social distancing and face mask detection combine video with AI-powered analytics to detect and analyze statistical patterns on how people are complying with policies around max occupancy rates, social distancing and the use of face masks. Providence Health care works closely with multidisciplinary teams at University of British Columbia (UBC), specifically the Department of Computing Science and the Computer Vision Lab. The model is available in public beta subject to further evaluation and training. This model is not intended for medical use.
    • This machine learning model uses computer vision to detect aggregate level of face mask use in waiting rooms within hospital waiting rooms. The model is currently in the pilot phase at St. Paul's Hospital in Vancouver, Canada in order to ensure physical distancing and compliance to infection control procedures for the safety of our patients, staff and visitors. The model utilizes SSD (Single Shot Detection) objection detection model and weights by applying a single neural network to the full image. No personally identifiable information is stored as part of the analysis.
    • SSD has two components: a backbone model and SSD head. Backbone model is a pre-trained image classification network as a feature extractor. The backbone in this model has 8 conv layers with 1.01M parameters. This model can extract semantic meaning from the input image while preserving the spatial structure of the image albeit at a lower resolution. Input size of the model is 260x260. The total model has only 24 layers with the location and classification layers counted. Code was inspired by https://github.com/AIZOOTech/FaceMaskDetection

    Amazon SageMaker model

    An Amazon SageMaker model package is a pre-trained machine learning model ready to use without additional training. Use the model package to create a model on Amazon SageMaker for real-time inference or batch processing. Amazon SageMaker is a fully managed platform for building, training, and deploying machine learning models at scale.

    Deploy the model on Amazon SageMaker AI using the following options:
    Deploy the model as an API endpoint for your applications. When you send data to the endpoint, SageMaker processes it and returns results by API response. The endpoint runs continuously until you delete it. You're billed for software and SageMaker infrastructure costs while the endpoint runs. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Deploy models for real-time inference  .
    Deploy the model to process batches of data stored in Amazon Simple Storage Service (Amazon S3). SageMaker runs the job, processes your data, and returns results to Amazon S3. When complete, SageMaker stops the model. You're billed for software and SageMaker infrastructure costs only during the batch job. Duration depends on your model, instance type, and dataset size. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Batch transform for inference with Amazon SageMaker AI  .
