@spec apply2(t(), [Evision.Detail.ImageFeatures.t()]) ::
  [Evision.Detail.MatchesInfo.t()] | {:error, String.t()}

Performs images matching.

Positional Arguments
  • self: Evision.Detail.FeaturesMatcher.t()

  • features: [Evision.Detail.ImageFeatures].

    Features of the source images

Keyword Arguments
  • mask: Evision.Mat.

    Mask indicating which image pairs must be matched

Return
  • pairwise_matches: [Evision.Detail.MatchesInfo].

    Found pairwise matches

The function is parallelized with the TBB library. @sa detail::MatchesInfo

Python prototype (for reference only):

apply2(features[, mask]) -> pairwise_matches
