How to Tesseract OCR in C# Alternatives with IronOCR

using IronOcr;
using System;

var ocr = new IronTesseract();
using var input = new OcrInput();
var pageindices = new int[] { 1, 2 };
input.LoadImageFrames(@"img\example.tiff", pageindices);
input.DeNoise();  //fixes digital noise
input.Deskew();   //fixes rotation and perspective

// there are dozens more filters, but most users wont need them
OcrResult result = ocr.Read(input);
Console.WriteLine(result.Text);

using IronOcr;
using System;

// Create an instance of the IronTesseract class for OCR processing
var ocr = new IronTesseract();

// Create an OcrInput object to load and preprocess images
using var input = new OcrInput();

// Specify which pages to extract from multi-page documents
var pageIndices = new int[] { 1, 2 };

// Load specific frames from a TIFF file
// IronOCR automatically detects and handles various image formats
input.LoadImageFrames(@"img\example.tiff", pageIndices);

// Apply automatic image enhancement filters
// These filters dramatically improve accuracy on imperfect scans
input.DeNoise();    // Removes digital artifacts and speckles
input.Deskew();     // Corrects rotation up to 15 degrees

// Perform OCR with enhanced accuracy algorithms
OcrResult result = ocr.Read(input);

// Access the extracted text with confidence metrics
Console.WriteLine(result.Text);

// Additional accuracy features available:
// - result.Confidence: Overall accuracy percentage
// - result.Pages[0].Words: Word-level confidence scores
// - result.Blocks: Structured document layout analysis
