Using the Tesseract OCR Source Code
- Download the Tesseract OCR source code from the Github repository.
- Install the dependencies listed in the INSTALL.md file.
- Compile the source code using the compilation instructions provided.
- After compilation, you can use the Tesseract command line tool to recognize text from images.
For example, you can use the following command to recognize text from an image file
example.png
:tesseract example.png output
This will generate a text file
output.txt
containing the recognized text. -
Alternatively, you can also use the Tesseract API to integrate Tesseract OCR into your own applications. For example, the following code snippet shows how to recognize text from an image file using the Tesseract API:
#include <tesseract/baseapi.h> #include <leptonica/allheaders.h> tesseract::TessBaseAPI api; api.Init(NULL, "eng"); Pix* image = pixRead("example.png"); api.SetImage(image); api.Recognize(NULL); char* text = api.GetUTF8Text(); printf("Recognized text: %s\n", text);
Output:
Recognized text: This is an example image.
