阿拉伯語、波斯語和烏爾都語語言包無法辨識阿拉伯數字?
這是 Tesseract 語言包的已知問題。
以下語言包或許有助於解決阿拉伯數字的顯示問題: Shreeshrii 的 Tessdata 阿拉伯語
然後可以將其與IronOCR功能結合使用,載入自訂語言套件: IronOCR自訂語言範例
using IronOcr;
class ArabicNumeralOCR
{
static void Main(string[] args)
{
// Initialize a new instance of IronTesseract for OCR
var Ocr = new IronTesseract();
// Load the custom Tesseract language file for better numeral recognition
Ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata");
// Specify the image input for OCR processing
using (var Input = new OcrInput(@"images\image.png"))
{
// Execute the OCR process on the input image
var Result = Ocr.Read(Input);
// Output the recognized text
Console.WriteLine(Result.Text);
}
}
}
using IronOcr;
class ArabicNumeralOCR
{
static void Main(string[] args)
{
// Initialize a new instance of IronTesseract for OCR
var Ocr = new IronTesseract();
// Load the custom Tesseract language file for better numeral recognition
Ocr.UseCustomTesseractLanguageFile("custom_tesseract_files/custom.traineddata");
// Specify the image input for OCR processing
using (var Input = new OcrInput(@"images\image.png"))
{
// Execute the OCR process on the input image
var Result = Ocr.Read(Input);
// Output the recognized text
Console.WriteLine(Result.Text);
}
}
}

注意:此 C# 範例示範如何在IronOCR中使用自訂 Tesseract 語言檔案來提高影像中阿拉伯數字的辨識率。 它假定您已經下載了相應的語言包並將其放置在指定位置。 請務必安裝IronOCR並在生產代碼中加入必要的錯誤處理。
