A CNN that actively detects if the user has worn a mask or not. That's it! As simple as that xD

MaskDetection-COVID-19

---

Introduction

---

MaskDetection-COVID-19 is a project that aims to solve the problem of identifying if someone has worn a mask or not. It is based on Convolutional Neural Network Architecture(CNN) and it is trained and integrated with computer vision technology to actively identify that if some user has worn a mask or not.
