Changed paths:
M filters/LOFFilter.cpp
Log Message:
-----------
Use Eigen SparseMatrix to store knn indices and distances in LOF filter (#3205)
* Use Eigen SparseMatrix to store knn indices and distances in LOF filter
Avoiding the repeated knnSearch in each separate pass results in a 3x
speed up.
Add several Eigen headers that have been relicensed from LGPL to MPL2
(see
https://gitlab.com/libeigen/eigen/-/commit/1dc1677d525b1df3cc32b3df5cd816e150b07185)
since our last refresh.
* Forego use of SparseMatrix and stick with std::map
