[DMP 2024]: Identify and retrieve beneficiary details through face recognition

[drtechie]

Ticket Contents

Description

Digital Bharat Collaborative (DBC) is an initiative of Piramal Swasthya, the healthcare arm of the Piramal Foundation. DBC's focus areas include building a robust digital public health delivery platform, improving data-driven governance and empowering healthcare workers.

Health and Wellness Centre (HWC) Mobile Application is developed by DBC to meet all Comprehensive Primary Health Care (CPHC) services as per the guidelines of Ayushman Bharat Digital Mission (ABDM). Health and Wellness Centres are aimed to deliver Comprehensive Primary Health Care, that includes preventive, promotive, curative, rehabilitative and palliative care, with a focus on wellness and the delivery of an expanded range of services closer to the community.

There are challenges in the field during the revisit of patients. When a patient revisits a centre, he/she must be looked up from the database in the most efficient and easiest way possible. The health worker should be able to fetch the details of the patient to prevent re-registration and thereby data duplication. By integrating facial recognition into the app, Community Health Officers (CHO) can quickly retrieve the registered patient's details, prefill the revisit form, look up medical history and prevent duplicate registrations.

The addition of this feature will ease the workflow of hundreds of health workers and indirectly ease the process of revisiting for thousands of beneficiaries.

Goals & Mid-Point Milestone

Goals

• [ ] Research and identify face recognition models that can work offline
• [ ] Collect and store face recognition data from a picture
• [ ] Search the face with saved facial biometric data
• [ ] [Goals Achieved By Mid-point Milestone are above]
• [ ] Lookup for the existing beneficiary in DB with the matched face
• [ ] Implement UI-UX elements for integrating the capture and recognition of images in the registration form

Setup/Installation

https://github.com/PSMRI/HWC-Mobile-App

Expected Outcome

• Capture and store facial recognition data in case of first registration
• Capture face and search beneficiaries from the existing registry of facial data in case of re-visit
• User-intuitive UI-UX to prefill data for a beneficiary in case of a revisit.

Acceptance Criteria

• Implement robust security measures to protect patient data, especially facial biometrics.
• The solution must work offline.

Implementation Details

This repo is a good starting point for the implementation.

At a high level, the following may be the implementation steps:

1. Launch Camera with lower resolution setting - Take a photo (you could also take a frame from the camera feed.
2. Find the face in the photo and collect bounding box coordinates ( as a Rect ) using MLKit.
3. Crop the face from the photo using the bounding box coordinates.
4. Feed the cropped face to the FaceNet model to generate embeddings. Your output will be an 128 dimensional vector of the given face
5. Load the list of patient IDs, names and their vectors to perform the face search on. This data set should be specific to the health workers' location and be cached for offline use.
6. Compare the photo vector with the list using  either L2norm or cosine similarity
7. If there are close matches - show the list of patients that matched closely along with a thumbnail of their photo.
8. if the user chooses an already registered patient -> start a new visit for that patient.
9. If there are no matches or the user chooses -register this as a new patient.
10. Save a thumbnail of the photo and features against a new patient ID

[Thejas775]

Hi @drtechie I am interested in working on this project. Let me introduce myself. I am Thejas Elandassery from Indian Institute of Technology Madras.I have experience with deepface, ML kit, Tensorflow Lite, CameraX and native android development in kotlin. I have done internships and freelance projects in android development. I have a question regarding this project.

1. Do we save the face details of the person on device or on some cloud database ?

For offline loading of the model. We can train ml model and use tensorflow lite and open-cv for the work (another way of implementing this feature) or the FaceNet.

Thanks waiting for your reply.

Please allow me to work on this project and to explore more about computer vision.

[hlukare]

Wow, this project seems like a game-changer! Integrating facial recognition into the HWC Mobile App could truly revolutionize healthcare delivery, making it more efficient and convenient for both health workers and patients. I'm excited to be a part of this innovative journey towards improving public health in our community!

Please allow me to work on this project and learn new things in the process.

can you please tell me how can I get access for this project?

Weekly Learnings & Updates

Week 1

• I researched various face recognition models for our project. FaceNet model by Google is the best fir for our purpose.
• Created a document containing all the research I have done so for.

  Week 2

• Added FaceNet model into the app.
• Room database cannot store vectors so the vector needs to be converted to string.

  Week 3

• Calculated Face vector for comparison using L2Norm.
• Implemented UI suggestions for matching of person and updated the recycler view.

  Week 4

• Pulled Data of the user whose face recognition had matching results and continue the flow for the registration.
