+# PJM/IA – Police Interview Emotion Analysis System
+
+## Overview
+
+PJM/IA is an intelligent support platform designed to assist criminal investigators during interviews and interrogations through multimodal emotion analysis.
+
+The system combines multiple Artificial Intelligence approaches to analyze emotional behavior from:
+
+- Facial expressions (FER – Facial Emotion Recognition)
+- Voice tone (SER – Speech Emotion Recognition)
+- Natural language sentiment analysis
+
+In addition to emotion analysis, the platform automates the administrative workflow associated with interviews by generating official reports automatically and producing annotated multimedia evidence.
+
+---
+
+## Main Features
+
+### Emotion Recognition
+
+- Facial Emotion Recognition (FER)
+- Speech Emotion Recognition (SER)
+- Sentiment Analysis using NLP
+
+### Automatic Documentation
+
+- Automatic generation of:
+  - Complaint Reports
+  - Witness Examination Reports
+  - Defendant Interrogation Reports
+- Automatic PDF report generation
+- Automatic transcription of interview audio into text
+
+### Multimedia Processing
+
+- Video analysis
+- Audio analysis
+- Live camera streaming analysis
+
+### Evidence Generation
+
+- Annotated interview videos
+- Emotion timeline tracking every 10 seconds
+- Structured interview archive system
+
+---
+
+# System Architecture
+
+The application is divided into modular components:

+# Installation
+
+## Windows Installation
+
+Run:
+
+```bash
+PJM_IA_Installer.exe
+```
+
+Follow the installation wizard until completion.
+
+The installer will:
+
+- Install the application
+- Create the required directories

+
+---
+
+# Authentication
+
+Default credentials for testing purposes:
+
+```txt
+Username: kl3z
+Password: 12345
+```
+
+---
+
+# Usage
+
+## 1. Load Subject Information
+
+The investigator must first load:
+
+- Citizen Card (CC)
+or
+- Military Registration Sheet (FM)
+
+This information is mandatory.
+
+---
+
+## 2. Configure Interview Metadata
+
+Optional metadata:
+
+- Interviewer
+- Date
+- Time
+- Location
+- City
+
+---
+
+## 3. Choose Analysis Mode
+
+### Video Analysis
+
+Processes prerecorded interrogation videos.
+
+### Audio Analysis
+
+Processes audio recordings.
+
+### Live Streaming
+
+Processes live camera input in real-time.
+
+Press:
+
+```txt
+Q
+```
+
+to stop recording.
+
+---
+
+# Generated Output
+
+After processing, the system generates:
+
+- Official PJM Word reports
+- PDF summary report
+- Full interview transcription
+- Emotion analysis reports
+- Annotated video files
+
+All files are stored automatically in:
+
+```txt
+/Corpus/<CC>_<DATE>_<TIME>/
+```
+
+Example:
+
+```txt
+12345678_2026-05-20_15-30-00
+```
+
+---
+
+# Interview Analysis
+
+The system performs emotion tracking every 10 seconds and correlates:
+
+- Facial expressions
+- Vocal tone
+- Speech sentiment
+
+This allows investigators to identify emotional variations throughout the interview.
+
+---
+
+# Technologies Used
+
+- Python
+- OpenCV
+- NLP
+- Speech Recognition
+- Machine Learning
+- Facial Recognition
+- Emotion Classification
+- Audio Signal Processing
+
+---
+
+# Research Context
