This repository contains the open-source code for real-time iris depth estimation using Google's MediaPipe Iris model. This innovative tool aims to provide proactive measures against the global rise of myopia (nearsightedness) by tracking and providing feedback on an individual's screen-viewing habits.
The method presented exploits the constant physical size of the human iris to estimate the distance between the observer and the screen using a standard RGB camera. Furthermore, this repository also includes a script to calculate real-world iris size based on images or videos taken at known distances, potentially enhancing the accuracy of depth estimation.
Ensure you have the following installed on your machine:
- Python 3.7+
- pip
- Git
Clone this repository to your local machine:
git clone https://github.com/MichaelBalas/DeepSight.git
Navigate to the cloned repository:
cd DeepSight
Install the required packages:
pip install -r requirements.txt
You will have to specify which device you're using so the focal length can be determined.
We provice typical focal lengths (in pixels) for most phones and computers, however you may have to adjust these values for your particular device.
Run the script with:
python irisDepth.py -d computer
This will initiate the webcam and start estimating the iris depth in real-time.
python irisDepth.py -i your_video.mp4 -d phone
This will load your pre-recorded video (taken by your phone) and start estimating the iris depth.
To calculate your real-world iris size, first take an image or video at a pre-specified distance from your device (e.g. 30cm, or a standard ruler). Then use:
python irisDiameter.py -i your_img.jpg -d phone -z 30
or
python irisDiameter.py -i your_video.mp4 -d phone -z 30
Remember to provide the known distance when capturing the image or video. The entirety of the video should be taken at a single distance, since iris size will be computed and averaged across all video frames.
