Implementations

impl FaceRecognizerSF

pub fn create( model: &str, config: &str, backend_id: i32, target_id: i32 ) -> Result<Ptr<FaceRecognizerSF>>

Creates an instance of this class with given parameters

Parameters

• model: the path of the onnx model used for face recognition
• config: the path to the config file for compability, which is not requested for ONNX models
• backend_id: the id of backend
• target_id: the id of target device

C++ default parameters

• backend_id: 0
• target_id: 0

pub fn create_def(model: &str, config: &str) -> Result<Ptr<FaceRecognizerSF>>

Creates an instance of this class with given parameters

Parameters

• model: the path of the onnx model used for face recognition
• config: the path to the config file for compability, which is not requested for ONNX models
• backend_id: the id of backend
• target_id: the id of target device

Note

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

• backend_id: 0
• target_id: 0
