Language detecton

To use language detection, install (aspose-ocr-language-classification-v1) advanced OCR model to your project.

Aspose.OCR for .NET can automatically identify the following languages and language families used on the provided image using Aspose.OCR.DetectLanguages method:

• Latin
• Cyrillic
• Arabic
• Chinese
• Japanese
• Korean
• Hindi
• Tamil
• Telugu
• Kannada

The method accepts the collection of images in any of the supported formats and returns them as a list of Aspose.OCR.LanguageDetectionOutput objects with the following properties:

Property	Type	Description
Source	string	The full path or URL of the source file. If the file is provided as a MemoryStream object, an array of pixels, or a Base64 string, this value will be empty.
Page	int	Page number. When working with single-page images, this value is always 0.
Languages	List<KeyValuePair<Aspose.OCR.Language, float>>	Lists the recognition languages detected in the image along with their probabilities.

Example

The following code sample demonstrates how to detect the image languages:

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
// Add an image to OcrInput object
Aspose.OCR.OcrInput input = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
input.Add("source.png");
// Detect languages
List<Aspose.OCR.LanguageDetectionOutput> result = recognitionEngine.DetectLanguages(input);
foreach (Aspose.OCR.LanguageDetectionOutput item in result)
{
	Console.WriteLine($"Image: {item.Source}");
	foreach (KeyValuePair<Aspose.OCR.Language, float> lang in item.Languages)
	{
		Console.WriteLine($"Language: {lang.Key}: {lang.Value}");
	}
}

The following code sample demonstrates how to recognize the image with auto detection languages:

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
// Add an image to OcrInput object
Aspose.OCR.OcrInput input = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
input.Add("source.png");
// Detect languages
List<Aspose.OCR.RecognitionResult> result = recognitionEngine.Recognize(input, new RecognitionSettings { 
                Language = Aspose.OCR.Language.Auto,
                LanguageDetectionLevel = Aspose.OCR.LanguageDetectionLevel.ByParagraph
                });
foreach (Aspose.OCR.RecognitionResult item in result)
{
		Console.WriteLine($"Text: {item.RecognitionText}");
}
