flann_FlannIndexTypeclass

Native enum entries for flann flann index type. Pass an entry to enum-typed arguments or its .value to numeric arguments.

flann_Indexclass

A nearest-neighbor search index over feature vectors. Choose index and search parameters for the descriptor type and distance metric.

flann_IndexParamsclass

Named configuration values used when constructing a FLANN nearest-neighbor index.

flann_KDTreeIndexParamsclass

Configuration for a randomized forest of kd-trees used to search floating-point descriptors.

flann_LinearIndexParamsclass

Configuration for exhaustive nearest-neighbor search over all descriptor rows.

flann_LshIndexParamsclass

Configuration for a locality-sensitive hashing index over binary descriptors.

flann_SearchParamsclass

Search configuration controlling the number of examined leaves, approximation tolerance and result ordering.

Constants

Use the named constant from cv. In particular, OpenCV 5 matrix type codes differ from OpenCV 4.
