Tesseract also allows us to add multi-frame images. It can extract text from images and convert it into a string. The Object Irontesseract which we created earlier can be used to get the images with the function called "Read" which will parse the image file and extract the result into the OCR result.
By using the OcrInput object method add, we may need to specify the available image path inside the function. Also, we are creating an object for OcrInput which allows us to add one or more image files. On the above line of code, we are creating an object for Iron Tesseract.
The above is an example of the Tesseract 5 API which allows us to convert image files into text. Using (var Input = new Result = Ocr.Read(Input) Using the Tesseract Engine for Images var Ocr = new IronTesseract() // nothing to configure However, if we use this setting it will improve the performance of the OCR process using Tesseract. These settings are optional and are not required to use the OCR. This will allow us to add a set of special characters to the code, which in turn ensures that the Tesseract engine matches the unknown character with the available blacklist characters. We can add blacklist characters, something which increases speed and accuracy. We are also able to specify the type of setting to improve the accuracy of the Tesseract OCR. With Iron Tesseract we are also able to specify Tesseract versions such as Tesseract 5, Tesseract 4, Tesseract 3, etc.
Other languages available in the image will be considered as unknown characters.

Based on the requirement we can use it in the code The normal method leads to high accuracy but low performance. Best and fast are improved versions that will lead to high performance and lack accuracy. Tesseract OCR provides multiple options for a single language, which will also us to choose between them, normal, best, and fast. Once we set the language, it will read only the specified language. We can set language/secondary languages with Iron Tesseract.

The Tesseract 5 example below shows us how to convert an image into text. By "using" statement which allows us to import the IronOCR library in the code. Tesseract OCR can support more than 15 types of image format.īefore we start to write the code for the OCR process, we need to include the IronOCR library. We need to use Leptonica and its built-in support for Zlib, png, and tiff image formats for optical character recognition. Tesseract uses the Leptonica library for an opening input image. The Tesseract optical character recognition has been created by using C++, and a C++ runtime environment is required to run the Tesseract OCR engine. Optical Character Recognition Using the Tesseract Engine This library is supported by all the net frameworks. Now the Visual Studio project is ready to use on the code.

Next, the NuGet package Manager will download all the DLL files and also add the reference of the DLL file in the current project or default project in Visual Studio as a net project reference. Go to the NuGet package manager link (below) to learn more about the latest version of the Iron Ocr Tesseract library.
#Ocr tool tesseract install#
Press the Enter key and it will install the NuGet package in the Visual Studio project. Open the package manager console tab as in the image below. In Visual Studio: go to Tools-> NuGet package manager -> Package manager consoleĮnter the following code in the NuGet package manager to install the NuGet package.
Select the first result in the NuGet package manager dialog and click the install option. Select NuGet package manager from the menu and search for IRONOCR as a keyword. Next, go to the solution explorer in Visual Studio and left-click the project.
#Ocr tool tesseract update#
We are also able to update or change between various versions of NuGet packages. We can search for a wide variety of packages and download them. NuGet allows us to search and install a NuGet package. The NuGet package manager allows us to install packages from the NuGet server. Now the project will generate the structure for the selected application, and, if you have selected the console application, it will be open the program.cs file where you can enter the code and build/run the application. Also, select the required Dot Net Framework. BarCode can also be used on all types of applications, you can also use apps like Webform / MVC/ MVC Core on a net framework and Dot net core.Įnter a project name and select the file path in the appropriate text box in Visual Studio. Open Visual Studio and go to the File menu, select "new project", and then select Console Application/Windows forms/WPF Application. Tesseract allows us to convert any given images into text. Tesseract is one of the most accurate OCR engines. OCR stands for optical character recognition and is used to convert images, handwritten documents, printed text, and scanned documents into machine-encoded text.
