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.

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).

| cv.detail.AffineBestOf2NearestMatcher( | [, full_affine[, try_use_gpu[, match_conf[, num_matches_thresh1]]]] | ) -> | <detail_AffineBestOf2NearestMatcher object> |
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 |
