C++ (Cpp) ParseDescriptors Examples

Example #1

File: main.cpp Project: alexanderkuk/gender-classifier

int main(int argc, char *argv[]) {
  SamplesDesctiptors descriptors =
    ParseDescriptors(TRAIN_IMAGES + GENDERS_FILENAME);

  cv::Mat features(descriptors.size(), 
                   THUMBNAIL_SIZE.width * THUMBNAIL_SIZE.height,
                   CV_32FC1);
  cv::Mat targets(descriptors.size(), 1, CV_32SC1);
  std::cout << "Parsing data" << std::endl;
  MakeData(descriptors, &features, &targets);
  CvSVM svm;
  std::cout << "Learning" << std::endl;
  Learn(features, targets, &svm);
  std::cout << "Saving model" << std::endl;
  svm.save(GENDERMODEL_FILENAME);
  // std::cout << QFoldTest(features, targets, 10) << std::endl;

  return 0;
}
