Aspose.OCR 22.6.0

Image Denoising Support via BNN OCR .NET API

Product Page | Docs | Demos | API Reference | Examples | Blog | Search | Free Support | Temporary License

It is a standalone OCR API that enhances your .NET apps to perform the OCR operation on JPEG, PNG, GIF, BMP & TIFF images for extraction of English, French, Spanish & Portuguese content.

Aspose.OCR for .NET not only provides the Optical Character Recognition engine but more. You can also apply Blur, Gaussian Blur, and Median filter to reduce noise before document recognition and can set the OcrEngine to ignore non-textual blocks, maintain correct text order during document text recognition & automatically correct spellings of the document text.

Image OCR API Features

• Programmatically detect, identify and read characters from images.
• Support English, French, Spanish and Portuguese text.
• Detect and read popular font faces such as Arial, Times New Roman, Courier New, Tahoma, Calibri & Verdana.
• Supports regular, bold, and italic font styles.
• Scan the whole image or only a specific portion of the image.
• Scan rotated images.
• Application of various noise removal filters to assist image recognition.

What's new in v22.6.0

Improved OCR Performance Support

Previously the System.Drawing was being used which has now been replaced with Aspose.Drawing. This has improved the OCR performance and cross-platform support.

Better Detection of Tabular Structures in OCR

A new DetectAreasMode enumeration has been introduced that allows to choose a neural network for the automatic detection of table cells. The available values are; NONE, DOCUMENT, PHOTO, COMBINE, TABLE. The TABLE value detects table cells with text via OCR API.

The following C# code snippet demonstrates how to detect image containing tabular content using API:

using Aspose.OCR;

namespace ProgramOCR
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create instance of OCR API
            AsposeOcr api = new AsposeOcr();
            // Set license
            License lic = new License();
            lic.SetLicense("ASPOSE-LICENSE.lic");
            // Image path
            string image = "table.jpg";
            // Recognize
            RecognitioResult resultTable = api.RecognizeImage(image, new RecognitionSettings {DetectAreasMode = DetectAreasMode.TABLE});
            //Print recognition results
            Console.WriteLine(resultTable.RecognitionText);
        }
    }
}

New ML Model for Image Denoising in OCR

A new recognition setting has been introduced in the OCR API that you may enable or disable to perform automatic noise removal from the detected images. The specialized neural network removes dirt, glare, unwanted gradients, spots, noise, and scratches from the images.

Please note that we have implemented both the pre-processing and post-processing algorithms for Binarized Neural Network (BNN).

The following is a C# sample code to recognize image using automatics noise removal (denoising) via API:

using Aspose.OCR;

namespace ProgramOCR
{
    class Program
    {
        static void Main(string[] args)
        {
            // Create instance of OCR API
            AsposeOcr api = new AsposeOcr();
            // Set license
            License lic = new License();
            lic.SetLicense("ASPOSE-LICENSE.lic");
            // Image path
            string image = "noisy.jpg";
            // Recognize
            RecognitioResult result = api.RecognizeImage(image, new RecognitionSettings {AutoDenoising = false});
            //Print recognition results
            Console.WriteLine(result.RecognitionText);
        }
    }
}

Read Image Formats for OCR

Raster Formats: JPEG, PNG, GIF, BMP, TIFF

Platform Independence

You can use Aspose.OCR for .NET to develop applications in any development environment that targets the .NET Framework 2.0 and higher. This includes support for Mono and Client Profiles.

Get Started with Aspose.OCR for .NET

Are you ready to give Aspose.OCR for .NET a try? Simply execute Install-Package Aspose.OCR from Package Manager Console in Visual Studio to fetch the NuGet package. If you already have Aspose.OCR for .NET and want to upgrade the version, please execute Update-Package Aspose.OCR to get the latest version.

Execute the following code snippet to see how Aspose.OCR API performs with your own samples or simply check the GitHub Repository for other common usage scenarios.

Perform OCR on PNG Image via C# Code

// The path to the documents directory.
string dataDir = RunExamples.GetDataDir_OCR();

// Initialize an instance of AsposeOcr
AsposeOcr api = new AsposeOcr();

// Recognize image
string result = api.RecognizeImage(dataDir + "sample.png");

// Display the recognized text
Console.WriteLine(result);
