About NeuroGuardAI

NeuroGuardAI is a web app that detects faces in photos and recognizes emotions using neural networks.

What it does

Upload a clear image containing a face (JPEG, PNG, or WebP). The app finds the face and returns a breakdown of emotions with confidence scores. Supported emotions include happiness, sadness, anger, surprise, fear, disgust, and neutral.

How it works

The app uses the FER (Facial Emotion Recognition) library with MTCNN for face detection and a deep learning model trained on facial expressions. Your image is processed on the server; no data is stored after the result is shown.

Tips for best results

• Use a front-facing photo with the face clearly visible.
• Good lighting and minimal obstructions (e.g. glasses, hands) help.
• Single-face images work best; if multiple faces are present, the first detected face is analyzed.
