Hello,
I have an image in which alphanumeric characters as also special characters
may appear. I have confiigured Tesseract to include only numeric characters
in the white list. However, when I process the image all characters get
recognised. Where am I going wrong? Here is my code:
///////////////////////////////////////////////////////////////////////////////////////////////////
BOOL bResult = TRUE;
tesseract::TessBaseAPI api;
ETEXT_DESC* monitor = NULL;
ETEXT_DESC* head = NULL;
bResult = api.SetVariable("classify_bln_numeric_mode", "T");
bResult = api.SetVariable("tessedit_char_blacklist",
"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ");
bResult = api.SetVariable("tessedit_char_whitelist", "0123456789");
bResult = api.Init("", "eng", tesseract::OEM_DEFAULT);
api.SetVariable("save_blob_choices", "T");
api.SetPageSegMode(static_cast<tesseract::PageSegMode>(7));
api.SetOutputName("out");
StartTimer();
api.SetImage((uchar*)(m_OrigImage.GetImage()->imageData),
m_OrigImage.Width(), m_OrigImage.Height(),
m_OrigImage.GetImage()->nChannels, m_OrigImage.GetImage()->widthStep);
int nResult = api.Recognize(monitor);
const char* out = api.GetUTF8Text();
//////////////////////////////////////////////////////////////////////////////////////////////////
This a VC8 program running on WIN XP.
Thanks,
Kishor Durve
