(A Computer Vision and Machine Learning Solution to implement Social Distancing and Mandatory Mask wearing to avoid the spread of the Covid 19 virus for TATA INNOVERSE SolverHunt 8.)


EYEXA is a Combined Computer Vision and Machine Learning Application that recognises a person and checks if he is maintaining social distancing or not , and also checks if he is wearing a mask or not simultaneously.

If any of the two above criteria fails then its alerts a user concerned with a warning sound , so the person violating can take necessary steps to minimise the spread of the virus.

EYEXA performs two primary functions using multi threading , OpenCV and ML

1. EYEXA uses yolov3 model to track a person and then does various internal computations to check all the person in the frame
are maintaining a proper social distancing norms or not . and display the number of person violating the social distancing norms.

2. EYEXA uses an custom trained model based on MobileNetV2 to train on images of person wearing/not_wearing a mask , and
predict the person in the camera feed is wearing a mask or not . It also uses a res10_300x300_sad_iter_140000.caffemodel to focus
on person face during the prediction.

Code creation in progress for automatically measuring the temperature of people using a thermal camera.
The software can be freely used for any creating applications that it is useful
for the automatic early-screening of fever symptoms.


The software first detect people with an off-the-shelf body pose detector and then extract location of the face where the temperature is measured. The software requires a known reference temperature and the value and position are provided by the user (this information is shown as a single small green circle on the image). It is possible to have the absolute temperature but you need an image from a thermal camera with correct radiometric calibration and radiometric exif data loaded into image.
