Finding text in an image

Aspose.OCR for .NET makes searching for text in images as easy as finding the text fragment in a string. In a single line of code, you can search for a case-sensitive or case-insensitive string, and even validate an image text against a pattern.

To search for a text in an image, use ImageHasText method of AsposeOcr class. The method either takes a text fragment or a regular expression and returns true if the text is found or false if not.

ImageHasText method allows you to optionally customize recognition accuracy, performance, and other settings.

Read image from path

Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
Aspose.OCR.RecognitionSettings recognitionSettings = new Aspose.OCR.RecognitionSettings();
recognitionSettings.Language = Aspose.OCR.Language.Ukr;
if(recognitionEngine.ImageHasText("source.png", "Aspose", recognitionSettings))
{
	Console.WriteLine(@"The image contains the word ""Aspose""");
}
else
{
	Console.WriteLine(@"The image doesn't contain the word ""Aspose""");
}

Read image from memory

Regex rx = new Regex(@"Aspose\.O(C|M)R", RegexOptions.IgnoreCase);
Aspose.OCR.AsposeOcr recognitionEngine = new Aspose.OCR.AsposeOcr();
Aspose.OCR.RecognitionSettings recognitionSettings = new Aspose.OCR.RecognitionSettings();
recognitionSettings.Language = Aspose.OCR.Language.Ukr;
if(recognitionEngine.ImageHasText("source.png", rx, recognitionSettings))
{
	Console.WriteLine(@"The image contains ""Aspose.OCR"" or ""Aspose.OMR""");
}
else
{
	Console.WriteLine(@"The image doesn't contain ""Aspose.OCR"" or ""Aspose.OMR""");
}
