Struct Detail_AffineBestOf2NearestMatcher 

Source 
pub struct Detail_AffineBestOf2NearestMatcher { /* private fields */ }
Expand description

Features matcher similar to cv::detail::BestOf2NearestMatcher which finds two best matches for each feature and leaves the best one only if the ratio between descriptor distances is greater than the threshold match_conf.

Unlike cv::detail::BestOf2NearestMatcher this matcher uses affine transformation (affine transformation estimate will be placed in matches_info).

Implementations§

Source§

impl Detail_AffineBestOf2NearestMatcher

Source

pub fn new( full_affine: bool, try_use_gpu: bool, match_conf: f32, num_matches_thresh1: i32, ) -> Result<Detail_AffineBestOf2NearestMatcher>

Constructs a “best of 2 nearest” matcher that expects affine transformation between images

§Parameters
  • full_affine: whether to use full affine transformation with 6 degress of freedom or reduced transformation with 4 degrees of freedom using only rotation, translation and uniform scaling
  • try_use_gpu: Should try to use GPU or not
  • match_conf: Match distances ration threshold
  • num_matches_thresh1: Minimum number of matches required for the 2D affine transform estimation used in the inliers classification step
§See also

cv::estimateAffine2D cv::estimateAffinePartial2D

§C++ default parameters
  • full_affine: false
  • try_use_gpu: false
  • match_conf: 0.3f
  • num_matches_thresh1: 6

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 unsafe in a general case as it leads to having non-exclusive mutable access to the internal data, but it can be useful for some performance sensitive operations. One example of an OpenCV function that allows such in-place modification is imgproc::threshold. Read more
