Struct opencv::dpm::DPMDetector

pub struct DPMDetector { /* private fields */ }

This is a C++ abstract class, it provides external user API to work with DPM.

Implementations

impl DPMDetector

pub fn create( filenames: &Vector<String>, class_names: &Vector<String> ) -> Result<Ptr<DPMDetector>>

Load the trained models from given .xml files and return cv::Ptr<DPMDetector>.

Parameters

• filenames: A set of filenames storing the trained detectors (models). Each file contains one model. See examples of such files here /opencv_extra/testdata/cv/dpm/VOC2007_Cascade/.
• classNames: A set of trained models names. If it’s empty then the name of each model will be constructed from the name of file containing the model. E.g. the model stored in “/home/user/cat.xml” will get the name “cat”.

C++ default parameters

• class_names: std::vectorstd::string()

pub fn create_def(filenames: &Vector<String>) -> Result<Ptr<DPMDetector>>

Load the trained models from given .xml files and return cv::Ptr<DPMDetector>.

Parameters

• filenames: A set of filenames storing the trained detectors (models). Each file contains one model. See examples of such files here /opencv_extra/testdata/cv/dpm/VOC2007_Cascade/.
• classNames: A set of trained models names. If it’s empty then the name of each model will be constructed from the name of file containing the model. E.g. the model stored in “/home/user/cat.xml” will get the name “cat”.

Note

This alternative version of DPMDetector::create function uses the following default values for its arguments:

• class_names: std::vectorstd::string()
