pub fn as_raw_mut_PtrOfLBPHFaceRecognizer(&mut self) -> *mut c_void

Trait Implementations

impl AlgorithmTrait for PtrOfLBPHFaceRecognizer

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

fn clear(&mut self) -> Result<()>

Clears the algorithm state

fn read(&mut self, fn_: &FileNode) -> Result<()>

Reads algorithm parameters from a file storage

impl AlgorithmTraitConst for PtrOfLBPHFaceRecognizer

fn as_raw_Algorithm(&self) -> *const c_void

fn write(&self, fs: &mut FileStorage) -> Result<()>

Stores algorithm parameters in a file storage

fn write_with_name(&self, fs: &Ptr<FileStorage>, name: &str) -> Result<()>

simplified API for language bindings Stores algorithm parameters in a file storage

fn empty(&self) -> Result<bool>

Returns true if the Algorithm is empty (e.g. in the very beginning or after unsuccessful read

fn save(&self, filename: &str) -> Result<()>

Saves the algorithm to a file. In order to make this method work, the derived class must implement Algorithm::write(FileStorage& fs).

fn get_default_name(&self) -> Result<String>

Returns the algorithm string identifier. This string is used as top level xml/yml node tag when the object is saved to a file or string.

impl FaceRecognizer for PtrOfLBPHFaceRecognizer

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

fn train(
    &mut self,
    src: &dyn ToInputArray,
    labels: &dyn ToInputArray
) -> Result<()>

Trains a FaceRecognizer with given data and associated labels.

fn update(
    &mut self,
    src: &dyn ToInputArray,
    labels: &dyn ToInputArray
) -> Result<()>

Updates a FaceRecognizer with given data and associated labels.

fn read(&mut self, filename: &str) -> Result<()>

Loads a FaceRecognizer and its model state.

fn read_1(&mut self, fn_: &FileNode) -> Result<()>

Loads a FaceRecognizer and its model state.

fn set_label_info(&mut self, label: i32, str_info: &str) -> Result<()>

Sets string info for the specified model’s label.

fn set_threshold(&mut self, val: f64) -> Result<()>

Sets threshold of model

impl FaceRecognizerConst for PtrOfLBPHFaceRecognizer

fn as_raw_FaceRecognizer(&self) -> *const c_void

fn predict_label(&self, src: &dyn ToInputArray) -> Result<i32>

if implemented - send all result of prediction to collector that can be used for somehow custom result handling

fn predict(
    &self,
    src: &dyn ToInputArray,
    label: &mut i32,
    confidence: &mut f64
) -> Result<()>

Predicts a label and associated confidence (e.g. distance) for a given input image.

fn predict_collect(
    &self,
    src: &dyn ToInputArray,
    collector: Ptr<dyn PredictCollector>
) -> Result<()>

if implemented - send all result of prediction to collector that can be used for somehow custom result handling

fn write(&self, filename: &str) -> Result<()>

Saves a FaceRecognizer and its model state.

fn write_1(&self, fs: &mut FileStorage) -> Result<()>

Saves a FaceRecognizer and its model state.

fn empty(&self) -> Result<bool>

fn get_label_info(&self, label: i32) -> Result<String>

Gets string information by label.

fn get_labels_by_string(&self, str: &str) -> Result<Vector<i32>>

Gets vector of labels by string.

fn get_threshold(&self) -> Result<f64>

threshold parameter accessor - required for default BestMinDist collector
