Implementations
sourceimpl Vocabulary
impl Vocabulary
Vocabulary API
sourcepub fn transform(&self, features: &[Desc]) -> Result<BoW, BowErr>
pub fn transform(&self, features: &[Desc]) -> Result<BoW, BowErr>
Transform a vector of binary descriptors into its bag of words representation with respect to the Vocabulary. Descriptor is l1 normalized. Returns Err if features is empty.
sourcepub fn transform_with_direct_idx(
&self,
features: &[Desc]
) -> Result<(BoW, DirectIdx), BowErr>
pub fn transform_with_direct_idx(
&self,
features: &[Desc]
) -> Result<(BoW, DirectIdx), BowErr>
Transform a vector of binary descriptors into its bag of words representation with respect to the Vocabulary. Descriptor is l1 normalized. Returns Err if features is empty.
Also provides “direct index” from the features to their corresponding nodes in the Vocabulary tree.
The direct index for feature[i]
is di = DirectIdx[i]
where
di.len() <= l
(number of levels), and di[j]
is the id of the node matching feature[i]
at level j
in the Vocabulary tree.
sourcepub fn create(features: &[Desc], k: usize, l: usize) -> Self
pub fn create(features: &[Desc], k: usize, l: usize) -> Self
Build a vocabulary from a collection of descriptors.
Args:
- k: Branching factor
- l: Max number of levels (Should be <= 5)
