Handling Equations with IronOCR
Can IronOCR read equations?
IronOCR uses Tesseract 4/5 and should work quite well with reading equations out of the box, though you may want to experiment with the detailed configuration options:

You may also add custom language packs to IronOCR: Learn about custom language packs
There is also an EQU Equation Detection Language Pack: EQU Language Pack
// C# Example to demonstrate reading equations using IronOCR
using IronOcr; // Import the IronOcr namespace
public class EquationOcrExample
{
public void ReadEquations(string imagePath)
{
// Instantiate the IronTesseract object
var Ocr = new IronTesseract();
// Load the custom EQU language for better equation detection
Ocr.Language = Ocr.Languages.Add("equ");
// Read and OCR the image containing equations
using (var Input = new OcrInput(imagePath))
{
// Extract OcrResult from the image
var Result = Ocr.Read(Input);
// Output the contents of the OCR result as text
System.Console.WriteLine(Result.Text);
}
}
}// C# Example to demonstrate reading equations using IronOCR
using IronOcr; // Import the IronOcr namespace
public class EquationOcrExample
{
public void ReadEquations(string imagePath)
{
// Instantiate the IronTesseract object

{
// Extract OcrResult from the image
var Result = Ocr.Read(Input);
// Output the contents of the OCR result as text
System.Console.WriteLine(Result.Text);
}
}
}' C# Example to demonstrate reading equations using IronOCR
Imports IronOcr ' Import the IronOcr namespace
Public Class EquationOcrExample
Public Sub ReadEquations(ByVal imagePath As String)
' Instantiate the IronTesseract object
Dim Ocr = New IronTesseract()

In the example above, IronOCR utilizes the Tesseract OCR engine to read equations from an image file. The custom language pack for equations (equ) is loaded to improve detection accuracy. The ReadEquations method accepts a file path to the image containing equations, performs OCR, and outputs the recognized text.
