Document Scanner and Converter App - BSc IT Project Guide
1. Introduction
The Document Scanner and Converter App is a mobile or desktop application that allows users to scan physical documents using their device camera, process the images for clarity, and convert the scanned content into various digital formats such as PDF, DOCX, and image files. It is a useful tool for students, professionals, and businesses to digitize paperwork efficiently.
2. Project Objectives
- To create a user-friendly app for scanning and digitizing
documents.
- To enable users to convert scanned images into PDF and other formats.
- To implement Optical Character Recognition (OCR) for text extraction.
- To support file sharing and storage options.
- To ensure high-quality image processing and file compression.
3. System Modules
Key modules include:
a. Camera Access and Document Scanning
b. Image Enhancement and Cropping
c. OCR (Text Extraction)
d. File Conversion (PDF, DOCX, JPG)
e. File Manager (Rename, Delete, Organize)
f. Sharing and Export Options
g. Settings and Preferences
4. Technologies Used
- Frontend: Flutter / React Native / Java (Android)
- Backend: Local Storage and Optional Cloud Integration
- OCR Engine: Tesseract OCR
- Libraries: PDFKit, Image Processing Libraries (OpenCV, ML Kit)
- Tools: Android Studio, Firebase (optional for storage), Git
5. Development Methodology
The app is developed using Agile methodology. Iterative development cycles focus on core features first (scanning and saving), followed by enhancements like OCR and file export options.
6. System Design Overview
The system is designed with modular components for image capture, processing, OCR, and conversion. It uses an MVC or MVVM architecture pattern to separate logic, data, and UI components.
7. Testing
Testing includes:
- Unit Testing: Image capture, processing, and conversion modules
- UI Testing: Interface responsiveness and accessibility
- Integration Testing: End-to-end scan to export workflow
- Performance Testing: File size, speed, and OCR accuracy
8. Conclusion
The Document Scanner and Converter App provides a portable solution for digitizing and managing physical documents. Its efficiency and multi-format support make it a valuable tool in both academic and professional settings.
