Hi, I am using Tesseract 3.0.2, lately I found a memory leak from a very
basic tesseract recognition steps, I realized I missed a delete [] from
GetUTF8Text().
The problem is when I was trying to delete it, it crashes. May I know what
is happening here? I am following the sample from tesseract.
Below is a block of sample code.
tesseract::TessBaseAPI *myOCR = new tesseract::TessBaseAPI();
myOCR->SetPageSegMode(tesseract::PSM_AUTO);
if (myOCR->Init("./", "new+old")) {
std::cerr << "Could not initialize tesseract." << std::endl;
exit(1);
}
myOCR->SetVariable("tessedit_char_blacklist",
"abcdefghijklmnopqrstuvwxyz`~!@#$%^&*()_+-={}[]|\':;/?.<,>");
myOCR->SetVariable("tessedit_char_whitelist",
"ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789");
myOCR->SetImage((uchar*) plate_segments.data,
plate_segments.size().width, plate_segments.size().height,
plate_segments.channels(), plate_segments.step1());
myOCR->Recognize(0);
char* license_result = myOCR->GetUTF8Text();
delete [] license_result; <--- CAUSE CRASH???
