/** @brief The FLANN nearest neighbor index class. This class is templated with the type of elements for which
the index is built.
`Distance` functor specifies the metric to be used to calculate the distance between two points.
There are several `Distance` functors that are readily available:
@link cvflann::L2_Simple cv::flann::L2_Simple @endlink- Squared Euclidean distance functor.
This is the simpler, unrolled version. This is preferable for very low dimensionality data (eg 3D points)
@link cvflann::L2 cv::flann::L2 @endlink- Squared Euclidean distance functor, optimized version.
@link cvflann::L1 cv::flann::L1 @endlink - Manhattan distance functor, optimized version.
@link cvflann::MinkowskiDistance cv::flann::MinkowskiDistance @endlink - The Minkowsky distance functor.
This is highly optimised with loop unrolling.
The computation of squared root at the end is omitted for efficiency.
@link cvflann::MaxDistance cv::flann::MaxDistance @endlink - The max distance functor. It computes the
maximum distance between two vectors. This distance is not a valid kdtree distance, it's not
dimensionwise additive.
@link cvflann::HammingLUT cv::flann::HammingLUT @endlink - %Hamming distance functor. It counts the bit
differences between two strings using a lookup table implementation.
@link cvflann::Hamming cv::flann::Hamming @endlink - %Hamming distance functor. Population count is
performed using library calls, if available. Lookup table implementation is used as a fallback.
@link cvflann::Hamming2 cv::flann::Hamming2 @endlink- %Hamming distance functor. Population count is
implemented in 12 arithmetic operations (one of which is multiplication).
@link cvflann::HistIntersectionDistance cv::flann::HistIntersectionDistance @endlink - The histogram
intersection distance functor.
@link cvflann::HellingerDistance cv::flann::HellingerDistance @endlink - The Hellinger distance functor.
@link cvflann::ChiSquareDistance cv::flann::ChiSquareDistance @endlink - The chi-square distance functor.
@link cvflann::KL_Divergence cv::flann::KL_Divergence @endlink - The Kullback-Leibler divergence functor.
Although the provided implementations cover a vast range of cases, it is also possible to use
a custom implementation. The distance functor is a class whose `operator()` computes the distance
between two features. If the distance is also a kd-tree compatible distance, it should also provide an
`accum_dist()` method that computes the distance between individual feature dimensions.
In addition to `operator()` and `accum_dist()`, a distance functor should also define the
`ElementType` and the `ResultType` as the types of the elements it operates on and the type of the
result it computes. If a distance functor can be used as a kd-tree distance (meaning that the full
distance between a pair of features can be accumulated from the partial distances between the
individual dimensions) a typedef `is_kdtree_distance` should be present inside the distance functor.
If the distance is not a kd-tree distance, but it's a distance in a vector space (the individual
dimensions of the elements it operates on can be accessed independently) a typedef
`is_vector_space_distance` should be defined inside the functor. If neither typedef is defined, the
distance is assumed to be a metric distance and will only be used with indexes operating on
generic metric distances.
