OCR for Malayalam Characters

This project focuses on developing an Optical Character Recognition (OCR) system for recognizing both handwritten and printed Malayalam text from scanned PDF documents. The work is split into two parts:

  1. OCR for Handwritten Malayalam Characters
  2. OCR for Printed Malayalam and English Text

🔍 Project Overview

1. OCR for Handwritten Malayalam Characters

This module focuses on recognizing individual Malayalam characters from handwritten inputs. Key stages in this pipeline include:

  • Document Preprocessing
  • Text Segmentation
  • Character Recognition using Deep Learning

Highlights:

  • Achieved 91% accuracy at the character level.
  • Word/sentence recognition is feasible only with consistent spacing.
  • Built a minimalistic and scalable OCR system for handwritten character-level recognition.
  • Paves the way for digitization and automated data entry from handwritten documents.

2. OCR for Printed Malayalam and English Text

This module deals with the recognition of printed Malayalam (and English) text from scanned PDFs using a hybrid approach combining:

  • Tesseract OCR
  • Deep Learning-based Preprocessing Techniques

Key Techniques:

  • PDF to Image conversion
  • Grayscale and binary image preprocessing
  • Multi-threaded and language-optimized OCR execution

Highlights:

  • Parallelized OCR pipeline to enhance performance
  • Improved recognition accuracy over traditional OCR tools
  • Effective for multilingual documents

🛠️ Tech Stack

  • Python
  • OpenCV
  • Tesseract OCR
  • TensorFlow / Keras
  • Pillow
  • NumPy
  • PDF2Image
  • Matplotlib (for visualization)

🚀 Features

  • Robust recognition of handwritten Malayalam characters
  • Dual-language OCR system for printed Malayalam and English
  • Optimized for document digitization workflows
  • Scalable and minimalistic system architecture
