Struct KeyPointMatchParameters 

pub struct KeyPointMatchParameters {
    pub method: i32,
    pub ransac_reproj_threshold: f64,
    pub match_keep_ratio: f32,
    pub match_ratio: f32,

}

Parameters for keypoint matching and homography estimation.

Fields

method: i32

Method used in opencv::calib3d::find_homography(), typically opencv::calib3d::RANSAC.

ransac_reproj_threshold: f64

Reprojection threshold for RANSAC in find_homography(). A lower value makes RANSAC stricter (fewer matches kept), while a higher value is more lenient.

match_keep_ratio: f32

Ratio of best matches to keep after sorting by distance. Common values range from 0.5 to 0.8.

match_ratio: f32

Lowe’s ratio test threshold: how similar the best and second-best matches must be. Used in knn_match() to filter ambiguous matches. Common values range from 0.7 to 0.9.

border_mode: i32

Border mode used when warping images. Default: opencv::core::BORDER_CONSTANT.

border_value: Scalar

Border value used in warping. Default: opencv::core::Scalar::default().
