}Required methods
fn as_raw_mut_Facemark(&mut self) -> *mut c_void
Provided methods
fn load_model(&mut self, model: &str) -> Result<()>
fn load_model(&mut self, model: &str) -> Result<()>
A function to load the trained model before the fitting process.
Parameters
- model: A string represent the filename of a trained model.
Example of usage
ⓘ
facemark->loadModel("../data/lbf.model");fn fit(
&mut self,
image: &dyn ToInputArray,
faces: &dyn ToInputArray,
landmarks: &mut dyn ToOutputArray
) -> Result<bool>
fn fit(
&mut self,
image: &dyn ToInputArray,
faces: &dyn ToInputArray,
landmarks: &mut dyn ToOutputArray
) -> Result<bool>
Detect facial landmarks from an image.
Parameters
- image: Input image.
- faces: Output of the function which represent region of interest of the detected faces. Each face is stored in cv::Rect container.
- landmarks: The detected landmark points for each faces.
Example of usage
ⓘ
Mat image = imread("image.jpg");
std::vector<Rect> faces;
std::vector<std::vector<Point2f> > landmarks;
facemark->fit(image, faces, landmarks);
