Language detecton

Aspose.OCR for .NET can automatically analyze image content and identify the different types of layout blocks within it.

This functionality supports PNG, JPEG, BMP, TIFF, JFIF, and GIF images from files, streams, pixel arrays, and can bulk process folders and archives.

Pass one or more images as Aspose.OCR.OcrInput object to Aspose.OCR.DetectDocumentLayout method and get the layout blocks as Aspose.OCR.LayoutOutput object.

Aspose.OCR.LayoutOutput

This class stores a layout block detected in an image.

Property	Type	Description
Source	string	The full path to the file or URL, if applicable. Empty for images provided as a stream, byte array, or Base64.
Page	int	Page number for multi-page images.
Paragraphs	List<Aspose.OCR.ContentArea>	Detected paragraphs.
Images	List<Aspose.OCR.ContentArea>	Detected illustrations.
Headers	List<Aspose.OCR.ContentArea>	Detected headers.
Tables	List<Aspose.OCR.ContentArea>	Detected tables.
Lists	List<Aspose.OCR.ContentArea>	Detected lists.
Captions	List<Aspose.OCR.ContentArea>	Detected captions.
Equations	List<Aspose.OCR.ContentArea>	Detected equations.

Aspose.OCR.ContentArea

This class stores a layout block detected in an image.

Property	Type	Description
index	int	The sequential index of the content area, unique within the entire image.
image	MemoryStream	Image region (bitmap) with the content.
Rectangle	Aspose.OCR.Rectangle	The bounding rectangle of the content area.

Example

The following code demonstrates how to find and recognize tables in an image

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 layout
Aspose.OCR.LayoutOutput layout = recognitionEngine.DetectDocumentLayout(input)[0];
List<Aspose.OCR.ContentArea> tables = layout.Tables
// Recognize tables
Aspose.OCR.OcrInput tableAreas = new Aspose.OCR.OcrInput(Aspose.OCR.InputType.SingleImage);
foreach(Aspose.OCR.ContentArea table in tables)
{
	tableAreas.Add(tables.image)
}
Aspose.OCR.OcrOutput recognResult = api.Recognize(tableAreas);
