Struct opencv::flann::Index

pub struct Index { /* private fields */ }

Implementations

impl Index

pub fn default() -> Result<Index>

pub fn new( features: &impl ToInputArray, params: &impl IndexParamsTraitConst, dist_type: flann_distance_t ) -> Result<Index>

C++ default parameters

• dist_type: cvflann::FLANN_DIST_L2

pub fn new_def( features: &impl ToInputArray, params: &impl IndexParamsTraitConst ) -> Result<Index>

Note

This alternative version of [new] function uses the following default values for its arguments:

• dist_type: cvflann::FLANN_DIST_L2
