I am using tesseract 4 on a VC++ (MFC) app, to read text from images (A4
sizes). I noticed that while I using this app on several PCs (Win10 64 bit,
*GB RAM), the RAM occupied by my app (that use tesseract) is increasing on
and on. If I read 14 images, my app eat 470 MB, and if I didn't close the
app and read again all these 14 images, the RAM eaten by my app is
increasing until ~800MB, and if continue to read the same images, the RAM
is increasing on an on. Why is this happen ?
Here is the code that I am using for tesseract:
BOOL CMyClass::GetTextFromImage()
{
PIX* pix = NULL;
tesseract::TessBaseAPI* pTess = new tesseract::TessBaseAPI;
do
{
if (pTess->Init(...))
{
m_sError.Format(_T("OCRTesseract: Could not initialize tesseract."));
break;
}
// setup
// read image
PIX* pix = pixRead(m_sFileName);
if (! pix)
{
break;
}
// recognize
pTess->SetImage(pix);
}
while (FALSE);
// cleanup
// pTess->Clear();
// pTess->End();
delete pTess;
pTess = NULL;
pixDestroy(&pix);
return TRUE;
}
Is there anything wrong here ? Why is increasing RAM while I am using
tesseract ?
