Required methods

fn as_raw_FaceRecognizerSF(&self) -> *const c_void

Provided methods

fn align_crop(
    &self,
    src_img: &dyn ToInputArray,
    face_box: &dyn ToInputArray,
    aligned_img: &mut dyn ToOutputArray
) -> Result<()>

Aligning image to put face on the standard position

Parameters

• src_img: input image
• face_box: the detection result used for indicate face in input image
• aligned_img: output aligned image

fn match_(
    &self,
    _face_feature1: &dyn ToInputArray,
    _face_feature2: &dyn ToInputArray,
    dis_type: i32
) -> Result<f64>

Calculating the distance between two face features

Parameters

• _face_feature1: the first input feature
• _face_feature2: the second input feature of the same size and the same type as _face_feature1
• dis_type: defining the similarity with optional values “FR_OSINE” or “FR_NORM_L2”

C++ default parameters

• dis_type: FaceRecognizerSF::FR_COSINE
