Recognition

Reading text from any content in Aspose.OCR for .NET is as easy as calling a universal Aspose.OCR.AsposeOcr.Recognize method.

This method takes OcrInput object and optional recognition settings.

Recognition results are returned as a list of Aspose.OCR.RecognitionResult objects, that allow you to perform advanced manipulations with recognition results: automatically correct spelling, get image regions and save results in various formats.

Upgrading from previous versions

Starting with Aspose.OCR for .NET 23.3.1, this method replaces RecognizeImage, RecognizePdf, RecognizeTiff, RecognizeDjvu, RecognizeImageFromUri, RecognizeMultipleImages, and RecognizeImageFromBase64 recognition methods.

Example

The following code example shows how to extract text from multiple images:

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
// Add images to OcrInput object
Aspose.OCR.OcrInput input = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
input.Add("source1.png");
input.Add("source2.jpg");
// Set recognition language
Aspose.OCR.RecognitionSettings recognitionSettings = new Aspose.OCR.RecognitionSettings();
recognitionSettings.Language = Aspose.OCR.Language.Ukr;
// Recognize image
List<Aspose.OCR.RecognitionResult> results = recognitionEngine.Recognize(input, recognitionSettings);
foreach(Aspose.OCR.RecognitionResult result in results)
{
	Console.WriteLine(result.RecognitionText);
}
