Objective:

To automatically recognize, classify, and extract information from diagrams, flowcharts, and technical drawings using deep learning, enabling intelligent analysis and digitization of visual information.

Why Choose This Project:

• Diagram interpretation is essential in education, research, and engineering documentation.

• Reduces manual effort in understanding and annotating diagrams.

• Integrates computer vision, deep learning, and pattern recognition — highly practical for AI-based applications.

• Can be extended to convert diagrams into editable digital formats.

Key Features:

Technology Stack:

• Frontend: HTML, CSS, JavaScript, Bootstrap / React.js.

• Backend: Python with Flask or Django.

• Deep Learning / CV:

  • Model Frameworks: TensorFlow, Keras, or PyTorch.

  • Object Detection & Classification: YOLO, Faster R-CNN, or Mask R-CNN.

  • OCR: Tesseract OCR, EasyOCR.

• Database: MySQL / PostgreSQL / MongoDB for storing diagrams and extracted data.

• Optional: OpenCV for image preprocessing and noise reduction.

Working Flow:

1. Diagram Upload

   • Users upload diagram images or PDFs to the system.

2. Preprocessing

   • Image enhancement, resizing, noise removal, binarization, and edge detection.

3. Deep Learning-Based Detection

   • Detect shapes, arrows, and connectors using object detection models.

4. Text Extraction

   • Apply OCR to extract textual labels from diagrams.

5. Diagram Classification

   • Classify the diagram type (flowchart, circuit, UML, etc.) using a CNN-based classifier.

6. Output Generation

   • Generate structured output (JSON, SVG) representing diagram components and relationships.

7. Visualization & Dashboard

   • Display original diagram alongside recognized components and extracted text.

Main Modules:

1. Upload & Preprocessing Module

2. Shape & Symbol Detection Module

3. Text Extraction (OCR) Module

4. Diagram Classification Module

5. Output Generation & Visualization Module

Security Features:

• Secure upload to prevent malicious files.

• Role-based access to view sensitive diagrams.

• Data encryption for stored diagrams and extracted information.
