Please provide your valuable feedback for improvement. I hope this article has helped you understand the basic concept of extracting text from an image using Tesseract in C#.
#Open source ocr tool for .net pdf
Refer to the following code snippet that demonstrates PDF creation. We can also create a searchable PDF from scanned images, not plain text. String plainText = api.GetTextFromImage("C:\\Tapas\\ GetTextFromImage method can recognize text on a given bitmap, for instance. Also remember, the result of the OCR also changes with the quality of the image. The GetTextFromImage() method extracts text from. It is a customizable application and can extend overtime as contact management, project management, and human resource management. Then, I simply get the text from the image. Casebox is an Apache web-based document management system and 100 open source.

Next, refer to the typical C# code demonstrating how to extract plain text from the image. First, I have created an instance of OcrApi class to use Tesseract.NET API in the application. Now, let’s create the console application. The tessdata installed folder contains all files required for the Tesseract engine to work in the. 圆4\tesseract.dll is the 64-bit version of the Tesseract library.x86\tesseract.dll is the 32-bit version of the Tesseract library.contains XML documentation of the API.Also, a specific folder structure will be created. Refer to Figures 4 and 5.įigure 4: NuGet Package Manager with Tesseract.NET SDKįigure 5: NuGet Package Manager with Tesseract.NET SDKĪfter successful installation, Tesseract SDK will add the following DLLs in your project.

Run the command in Package Manager Console to install Tesseract.NET SDK or Select the NuGet package and install. Next, Install Tesseract.Net SDK through the Package Manager Console. You can open this by right-clicking the project and selecting Manage NuGet package.įigure 3: Visual Studio NuGet Package Manager To open the NuGet Manager, go to TOOLS> Library Package Manager> Package Manager Console, as indicated in Figure 3. Next, open NuGet Package Manager Console. You can see this in Figure 1.įigure 1: Visual Studio New Console Projectįigure 2 is the screen shot of the console application project.įigure 2: Visual Studio Sample Project Code NET Framework 4.5.įrom the Visual Studio New Project window, select Visual C#> Windows> Console Application and provide a name to the project-I called it “ProjectTesseract”-and save it. To develop the sample application, we will need Visual Studio and a basic knowledge of C# programming. It can read a wide variety of image formats and convert them to text in over 60 languages. Tesseract.NET SDK is a class library based on the tesseract-ocr project. NET Application to Extract Text from an Imageįor optical character recognition, we will be using the Tesseract.NET SDK.

In this article, I will demonstrate extracting image text using Tesseract and writing C# code under Windows OS. Tesseract OCR library is available for various different operating systems. It’s licensed under Apache 2.0 and has been supported by Google since 2006. Tesseract optical character recognition engine is one of the most accurate OCR engines currently available for. The OCR engine detects the characters present in the image and puts those characters into words, enabling developers to search and edit the content of the document. The show closes with skills a programmer needs to learn before diving into image recognition, such as some algebra and statistics and knowledge of data visualization, and some general tips.Tesseract engine optical character recognition (OCR) is a technology used to convert scanned paper documents, PDF files, and images to searchable text data. The host and guest also cover how to obtain enough and good datasets, and some of the common pitfalls.
