在 IronOCR 中使用阿拉伯数字

阿拉伯语、波斯语和乌尔都语语言包无法识别阿拉伯数字？

这是 Tesseract 语言包的一个已知问题。

以下语言包或许有助于解决阿拉伯数字的显示问题： Shreeshrii 的 Tessdata 阿拉伯语

然后可以将其与 IronOCR 功能结合使用，加载自定义语言包： IronOCR 自定义语言示例

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);
        }
    }
}

Imports IronOcr

Class ArabicNumeralOCR
    Shared Sub Main(args As String())
        ' Initialize a new instance of IronTesseract for OCR
        Dim 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 Input = New OcrInput("images\image.png")
            ' Execute the OCR process on the input image
            Dim Result = Ocr.Read(Input)

            ' Output the recognized text
            Console.WriteLine(Result.Text)
        End Using
    End Sub
End Class

Imports IronOcr

    Shared Sub Main(args As String())
        ' Initialize a new instance of IronTesseract for OCR

            ' Output the recognized text

        End Using
    End Sub
End Class

**注意：**此 C# 示例演示了如何在 IronOCR 中使用自定义 Tesseract 语言文件来提高图像中阿拉伯数字的识别率。它假定您已经下载了相应的语言包并将其放置在指定位置。请务必安装 IronOCR 并在生产代码中添加必要的错误处理。
