Hi, does anyone know how to save a custom object in .yml using FileStorage ?

According to the online document: http://docs.opencv.org/3.0-rc1/dd/d74...

I add the following snippet in my custom class ColorSample:

void ColorSample::read(const FileNode& node) {
mat = (Mat)node["mat"]; // Error: no matching function for call to cv::Mat::Mat(cv::FileNode)
loc = (Point)node["loc"]; // Error: no matching function for call to cv::Point_<int>::Point_(cv::FileNode)
color = (Scalar)node["color"];
}

Does anyone know how to solve the first two lines in ColorSample::read() ? Thanks

Hi there,

It should be a very simple question but I just can't found the way to get the class count from the SVM model instance, i.e., something like

Ptr<svm> svmModel = StatModel::load<svm>("xxx.yml");

int classCount = svmModel->getClassCount();

The variable classCount is stored in xxx.yml just like another variable VarConut. I found the method getVarCount() but fail to find getClassCount(), any suggestions? Thanks

Try: StatModel::load<svm>("YourSVMFile");
