fit()

virtual bool cv::face::FacemarkKazemi::fit ( InputArray  image, InputArray  faces, InputOutputArray  landmarks  )

pure virtual

This functions retrieves a centered and scaled face shape, according to the bounding rectangle.

Parameters

image	A variable of type cv::InputArray which stores the image whose landmarks have to be found
faces	A variable of type cv::InputArray which stores the bounding boxes of faces found in a given image.
landmarks	A variable of type cv::InputOutputArray which stores the landmarks of all the faces found in the imagefrom many ROIs

getFaces()

virtual bool cv::face::FacemarkKazemi::getFaces ( InputArray  image, OutputArray  faces  )

pure virtual

get faces using the custom detector

loadModel()

virtual void cv::face::FacemarkKazemi::loadModel ( String  filename )

pure virtual

This function is used to load the trained model..

Parameters

filename

A variable of type cv::String which stores the name of the file in which trained model is stored.

training() [1/2]

virtual void cv::face::FacemarkKazemi::training ( String  imageList, String  groundTruth  )

pure virtual

training the facemark model, input are the file names of image list and landmark annotation

training() [2/2]

virtual bool cv::face::FacemarkKazemi::training ( std::vector< Mat > &  images, std::vector< std::vector< Point2f > > &  landmarks, std::string  configfile, Size  scale, std::string  modelFilename = "face_landmarks.dat"  )

pure virtual

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.
