# Recognizing Characters

This code snippet shows how to load a font file, perform a default character recognition operation and perform a character recognition operation using a class filter.

## C++

```cpp
#include <eVision/EasyOcr/EasyOCR/EOCR.h>
```

```cpp
using namespace eVision;
// Image constructor
EImageBW8 srcImage;
// EOCR constructor
EOCR ocr;
// Load the font file
ocr.Load("myFont.ocr");
// ...
// Recognize the characters
std::string text = ocr.Recognize(&srcImage, 10, EOCRClass_AllClasses);
// Alternatively
// Define the character filter (2 letters and 3 digits)
std::vector<uint32_t> charFilter;
charFilter.push_back(EOCRClass_UpperCase);
charFilter.push_back(EOCRClass_UpperCase);
charFilter.push_back(EOCRClass_Digit);
charFilter.push_back(EOCRClass_Digit);
charFilter.push_back(EOCRClass_Digit);
// Recognize the characters with class filtering
text = ocr.Recognize(&srcImage, 10, charFilter);
```
