Implementations§

source§

impl FaceRecognizerSF

source

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
source

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

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

source§

impl<Mat> ModifyInplace for Mat
where Mat: Boxed,

source§

unsafe fn modify_inplace<Res>( &mut self, f: impl FnOnce(&Mat, &mut Mat) -> Res ) -> Res

Helper function to call OpenCV functions that allow in-place modification of a Mat or another similar object. By passing a mutable reference to the Mat to this function your closure will get called with the read reference and a write references to the same Mat. This is of course unsafe as it breaks the Rust aliasing rules, but it might be useful for some performance sensitive operations. One example of an OpenCV function that allows such in-place modification is imgproc::threshold. Read more
