This project involves developing a Mask Detection Application using MATLAB App Designer. The app uses image processing and machine learning techniques to detect whether a person is wearing a mask or not. The graphical interface (GUI) allows users to upload an activate a webcam, process the input, and display the detection results with clear visual indicators. A pre-trained deep learning model is integrated to classify images as “Proper mask” or “No Mask.” The project demonstrates the application of computer vision, deep learning, and GUI development in MATLAB to create a user-friendly detection app.
