🌟 Project Overview

Mental health disorders are a global crisis, yet timely and accurate assessment remains a major challenge. Traditional methods rely on subjective self-reporting, which is insufficient for detecting the true severity of a user's mental state.

MindCare AI solves this by combining four independent AI modalities into a single, unified platform. Rather than relying on one signal, the system fuses insights from:

📊 Behavioural Data — Lifestyle and physiological metrics (sleep, BMI, stress, heart rate, BP)
😐 Facial Emotion — Deep learning-based facial expression analysis from a live video feed
🎙️ Voice Emotion — Acoustic feature analysis from audio recordings to detect emotional tone
💬 Chat Text (NLP) — Conversational AI that extracts mental health indicators from natural language

The results are fused into a Final Severity Score (0–100) and a Risk Level (Low / Moderate / High / Critical), powering a personalized wellness dashboard with an AI therapist chatbot, daily tasks, mindfulness exercises, and curated video recommendations.

🌐 Live Demo

The project is fully deployed and accessible online. You can test the multimodal AI features without installing anything locally.

Frontend Application (Vercel): MindCare AI Web App
Backend API & Docs (Hugging Face): FastAPI Swagger UI

(Note: The backend is hosted on a free Hugging Face Space and may take 1-2 minutes to wake up from sleep upon initial load. The OTP email service is currently in DEMO mode; OTPs are generated and can be viewed in the backend logs or network response).

🤖 AI & Machine Learning Models

Step 1 — Behavioural Analysis (`Best_Mental_Behaviour_Model.pkl`)

Type: Scikit-learn ensemble classifier (Gradient Boosting)
Input Features: BMI category, sleep hours, sleep quality, physical activity level, stress level, heart rate, daily steps, systolic BP, diastolic BP
Output: Risk category (Low / Moderate / High) + confidence score + severity integer (0–100)
Encoders: Model_Encoders.pkl — handles label encoding and one-hot encoding for categorical inputs

Step 3 — Facial Emotion Detection (`Resnet_model_version_2.keras`)

Type: Fine-tuned ResNet Convolutional Neural Network (~303 MB)
Input: Video frames captured via the user's webcam, preprocessed with OpenCV
Output: Dominant facial emotion (e.g., Sad, Angry, Neutral, Happy, Fear, Disgust, Surprise) with per-class confidence scores
Severity Mapping: Emotions are mapped to a severity integer; negative valence emotions score higher

Step 4 — Voice Emotion Detection (`CNN_model.json` + `CNN_model.weights.h5`)

Type: Custom 1D/2D CNN trained on acoustic features
Feature Extraction: Librosa extracts MFCCs, chroma, spectral contrast, and mel-spectrogram features
Preprocessing: scaler2.pickle (StandardScaler) + encoder2.pickle (LabelEncoder)
Output: Voice emotion label + voice stress (Normal / Stressed / Highly Stressed) + voice mood + severity score

Step 2 — Chat NLP Analysis (`nlp_service.py`)

Sentiment Analysis: VADER (vaderSentiment) for rapid valence scoring + TextBlob for subjectivity
LLM Integration: OpenRouter API (Gemini model) for structured mental health Q&A
Extracted Signals: Problem description, duration, triggers, emotions, physical symptoms, coping strategy, support availability, daily life impact, intensity score
Risk Flagging: Automatic High/Critical flag for detected crisis indicators

Final Severity Fusion (`severity.py`)

Combines all four modality scores using a weighted average algorithm
Calculates overall risk level: Low (0–30) / Moderate (31–55) / High (56–79) / Critical (80–100)
Generates a natural language summary note for the dashboard

⚙️ Project Setup & Machine Learning Resources

Due to GitHub's file size limits, the large pre-trained multimodal models and the training datasets/scripts are hosted externally on Google Drive. To fully run or explore this project, please download the resource file below:

📥 Download MindCare Resources (Models & Training Data)

How to Setup the Downloaded Resources:

Once you download and extract MindCare_Resources.zip, you will find two folders inside. Please place them as instructed below:

Pre-trained_Models/: Move this entire folder directly inside the backend/ directory of this project. (These are the .keras, .h5, and .pkl files required for the FastAPI backend to run).
model_training/: Move this folder to the root directory of the project. (This contains the Jupyter notebooks, scripts, and datasets used to train the multimodal AI models).
