Class AffineBestOf2NearestMatcher

Namespace: OpenCvSharp.Detail

Assembly: OpenCvSharp.dll

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).

Constructors

AffineBestOf2NearestMatcher(bool, bool, float, int)

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

public AffineBestOf2NearestMatcher(bool fullAffine = false, bool tryUseGpu = false, float matchConf = 0.3, int numMatchesThresh1 = 6)

Parameters

fullAffine bool: 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
tryUseGpu bool: Should try to use GPU or not
matchConf float: Match distances ration threshold
numMatchesThresh1 int: Minimum number of matches required for the 2D affine transform estimation used in the inliers classification step
