Required Methods

fn as_raw_mut_FacemarkKazemi(&mut self) -> *mut c_void

Provided Methods

fn training(
    &mut self,
    images: &mut Vector<Mat>,
    landmarks: &mut Vector<Vector<Point2f>>,
    configfile: &str,
    scale: Size,
    model_filename: &str
) -> Result<bool>

This function is used to train the model using gradient boosting to get a cascade of regressors which can then be used to predict shape.

Parameters

• images: A vector of type cv::Mat which stores the images which are used in training samples.
• landmarks: A vector of vectors of type cv::Point2f which stores the landmarks detected in a particular image.
• scale: A size of type cv::Size to which all images and landmarks have to be scaled to.
• configfile: A variable of type std::string which stores the name of the file storing parameters for training the model.
• modelFilename: A variable of type std::string which stores the name of the trained model file that has to be saved.

Returns

A boolean value. The function returns true if the model is trained properly or false if it is not trained.

C++ default parameters

• model_filename: “face_landmarks.dat”

fn set_face_detector(
    &mut self,
    f: Option<Box<dyn FnMut(*const c_void, *const c_void) -> bool + Send + Sync + 'static>>
) -> Result<bool>

set the custom face detector

fn get_faces(
    &mut self,
    image: &dyn ToInputArray,
    faces: &mut dyn ToOutputArray
) -> Result<bool>

get faces using the custom detector
