Revision history [back]

Hello all, i'm trying to read sequence of.yml files and reshape them in single a single row then trying to concatenate in a single .yml file. here is my snap of code...

for (int i = 1; i <= 6; i++ )
        {
        sprintf_s(filename, "VocabularyLBP/Dictionary%d.yml", i);
       Mat feature;// , labels);;// = Mat::zeros(1, 100, CV_32FC1);
       FileStorage fs(filename, FileStorage::READ);
        fs["vocabulary"] >> feature;
        feature.convertTo(feature, CV_32FC1); 
        feature = feature.reshape(1, 1);

        trainData.push_back(feature);
        FileStorage fs1("trainData.yml", FileStorage::WRITE);
        fs1 << "vocabulary" << trainData;
        }

i'm not getting error, but getting data like..

vocabulary: !!opencv-matrix
   rows: 6
   cols: 7800
   dt: f
   data: [ -1.32703932e-03, -1.32703932e-03, -1.32703932e-03,
