過濾器精靈

VB C#

using IronOcr;
using System;

var ocrTesseract = new IronTesseract();

// WIZARD - If you are unsure which filters to use,
// use the debug-wizard to test all combinations:

string codeToRun = OcrInputFilterWizard.Run(@"images\image.png", out double confidence, ocrTesseract);
Console.WriteLine($"Confidence: {confidence}");
Console.WriteLine(codeToRun);

Imports IronOcr
Imports System

Private ocrTesseract = New IronTesseract()

' WIZARD - If you are unsure which filters to use,
' use the debug-wizard to test all combinations:

Private codeToRun As String = OcrInputFilterWizard.Run("images\image.png", Double confidence, ocrTesseract)
Console.WriteLine($"Confidence: {confidence}")
Console.WriteLine(codeToRun)

Install-Package IronOcr

過濾器精靈

IronOCR 包含一個OcrInputFilterWizard類，可自動評估預處理過濾器的組合，以最大限度地提高 OCR 置信度。如果您不確定哪些濾鏡能產生最佳效果，那麼這種方法非常理想。 OcrInputFilterWizard.Run(...)不會手動套用對比度、銳利化、二值化等，而是執行暴力掃描以找到最佳設置，並傳回最佳濾鏡組合或用於重現該設定的程式碼片段。
