Detailed 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 trasformation estimate will be placed in matches_info).

Constructor & Destructor Documentation

cv::detail::AffineBestOf2NearestMatcher::AffineBestOf2NearestMatcher	(	bool	full_affine = `false`,

	)

inline

Python:
	<detail_AffineBestOf2NearestMatcher object>	=	cv.detail_AffineBestOf2NearestMatcher(	[, full_affine[, try_use_gpu[, match_conf[, num_matches_thresh1]]]]	)

Constructs a "best of 2 nearest" matcher that expects affine trasformation 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
