AuroraScienceHub.Framework.Ocr

Optical Character Recognition (OCR) library based on Tesseract for extracting text from images.

Overview

Simple interface for performing OCR operations on images using the Tesseract engine. Supports full image text extraction and region-specific text recognition.

Key Features

  • Text Extraction - Extract text from images using Tesseract
  • Region-Based OCR - Read text from specific image regions
  • Multi-Language Support - Support for multiple languages via tessdata
  • Easy Integration - Simple dependency injection setup

Installation

dotnet add package AuroraScienceHub.Framework.Ocr

Prerequisites

Tesseract Installation

  • Linux: sudo apt update && sudo apt install libleptonica-dev libtesseract-dev
  • macOS: brew install leptonica tesseract
  • Windows: Download from Tesseract at UB Mannheim or choco install tesseract

Language Data

Place .traineddata files in ./tessdata folder. Download from tessdata repository.

Usage

Basic Setup

builder.Services.AddOcrServices();

Extract Text from Image

public class DocumentService
{
    private readonly IImageTextReader _textReader;

    public DocumentService(IImageTextReader textReader)
    {
        _textReader = textReader;
    }

    public string ExtractText(byte[] imageBytes)
    {
        return _textReader.ReadText(imageBytes);
    }

    public string ExtractFromRegion(byte[] imageBytes)
    {
        var region = new Rectangle(x: 100, y: 50, width: 200, height: 30);
        return _textReader.ReadText(imageBytes, region);
    }
}

API

public interface IImageTextReader
{
    string ReadText(byte[] imageBytes);
    string ReadText(byte[] imageBytes, Rectangle rectangle);
}

public class Rectangle
{
    public Rectangle(int x, int y, int width, int height);
}

Troubleshooting

  • Tesseract Not Found: Ensure Tesseract is installed and in PATH
  • Poor Recognition: Improve image quality or use appropriate language data
  • Performance Issues: Process specific regions instead of full images
