C++ (Cpp) RunNets Examples

Example #1

File: hybrid_neural_net_classifier.cpp Project: ErfanHasmin/scope-ocr

// return the cost of being a char
int HybridNeuralNetCharClassifier::CharCost(CharSamp *char_samp) {
  // it is by design that a character cost is equal to zero
  // when no nets are present. This is the case during training.
  if (RunNets(char_samp) == false) {
    return 0;
  }

  return CubeUtils::Prob2Cost(1.0f - net_output_[0]);
}

Example #2

File: hybrid_neural_net_classifier.cpp Project: ErfanHasmin/scope-ocr

// classifies a charsamp and returns an alternate list
// of chars sorted by char costs
CharAltList *HybridNeuralNetCharClassifier::Classify(CharSamp *char_samp) {
  // run the needed nets
  if (RunNets(char_samp) == false) {
    return NULL;
  }

  int class_cnt = char_set_->ClassCount();

  // create an altlist
  CharAltList *alt_list = new CharAltList(char_set_, class_cnt);
  if (alt_list == NULL) {
    return NULL;
  }

  for (int out = 1; out < class_cnt; out++) {
    int cost = CubeUtils::Prob2Cost(net_output_[out]);
    alt_list->Insert(out, cost);
  }

  return alt_list;
}

Example #3

// classifies a charsamp and returns an alternate list
// of chars sorted by char costs
CharAltList *ConvNetCharClassifier::Classify(CharSamp *char_samp) {
  // run the needed nets
  if (RunNets(char_samp) == false) {
    return NULL;
  }

  int class_cnt = char_set_->ClassCount();

  // create an altlist
  CharAltList *alt_list = new CharAltList(char_set_, class_cnt);
  if (alt_list == NULL) {
    fprintf(stderr, "Cube WARNING (ConvNetCharClassifier::Classify): "
            "returning emtpy CharAltList\n");
    return NULL;
  }

  for (int out = 1; out < class_cnt; out++) {
    int cost = CubeUtils::Prob2Cost(net_output_[out]);
    alt_list->Insert(out, cost);
  }

  return alt_list;
}

Example #4

// return the cost of being a char
int ConvNetCharClassifier::CharCost(CharSamp *char_samp) {
  if (RunNets(char_samp) == false) {
    return 0;
  }
  return CubeUtils::Prob2Cost(1.0f - net_output_[0]);
