@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

@spec collectGarbage(Keyword.t()) :: any() | {:error, String.t()}

@spec collectGarbage(t()) :: t() | {:error, String.t()}

Frees unused memory allocated before if there is any.

Positional Arguments
