Hi,
I went through lot of pages to find how to generate character level
confidence but with now success. I have also include
SetVariable("save_best_choices", "T") but it still des not work. Can
somebody please debug the code. Thanks a lot.
Code:
#include "allheaders.h"
#include "baseapi.h"
#include "strngs.h"
#include "tesseractmain.h"
#include "tprintf.h"
int main(int argc, char **argv) {
const char *lang="eng";
const PIX *pixs;
if ((pixs = pixRead(argv[1])) == NULL) {
printf("Unsupported image type.\n");
exit(3);
}
tesseract::TessBaseAPI api;
api.SetVariable("save_best_choices", "T");
api.SetImage(pixs);
int rc = api.Init(argv[0], lang);
api.Recognize(NULL);
tesseract::ResultIterator* ri = api.GetIterator();
tesseract::ChoiceIterator* ci;
if(ri != 0)
{
do
{
const char* symbol = ri->GetUTF8Text(tesseract::RIL_SYMBOL);
// printf("======================");
if(symbol != 0)
{
float conf = ri->Confidence(tesseract::RIL_SYMBOL);
printf("\nnext symbol: %s, conf: %f", symbol, conf,
"\n");
const tesseract::ResultIterator itr = *ri;
ci = new tesseract::ChoiceIterator(itr);
do
{
printf("----");
const char* choice = ci->GetUTF8Text();
printf("\t\t%s conf: %f", choice, ci->Confidence());
}
while(ci->Next());
delete ci;
}
delete[] symbol;
} while((ri->Next(tesseract::RIL_SYMBOL)));
}
return 0;
}
Output:
next symbol: c, conf: 85.844711---- (null) conf: 0.000000
next symbol: o, conf: 85.844711---- (null) conf: 0.000000
next symbol: m, conf: 85.844711---- (null) conf: 0.000000
next symbol: Q, conf: 0.000000---- (null) conf: 0.000000
Does anybody see a problem in it??
Thanks in advance
