Class AffineBestOf2NearestMatcher

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).

AffineBestOf2NearestMatcher(Boolean, Boolean, Single, Int32)

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

Declaration
public AffineBestOf2NearestMatcher(bool fullAffine = false, bool tryUseGpu = false, float matchConf = 0.3F, int numMatchesThresh1 = 6)
Parameters
Type Name Description
System.Boolean fullAffine

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
System.Boolean tryUseGpu

Should try to use GPU or not
System.Single matchConf

Match distances ration threshold
System.Int32 numMatchesThresh1

Minimum number of matches required for the 2D affine transform estimation used in the inliers classification step
