pub trait BOWTrainer: BOWTrainerConst {
    // Required method

}

Abstract base class for training the bag of visual words vocabulary from a set of descriptors.

For details, see, for example, Visual Categorization with Bags of Keypoints by Gabriella Csurka, Christopher R. Dance, Lixin Fan, Jutta Willamowski, Cedric Bray, 2004. :

Required Methods

fn as_raw_mut_BOWTrainer(&mut self) -> *mut c_void

Provided Methods

fn add(&mut self, descriptors: &Mat) -> Result<()>

Adds descriptors to a training set.

Parameters

• descriptors: Descriptors to add to a training set. Each row of the descriptors matrix is a descriptor.

The training set is clustered using clustermethod to construct the vocabulary.

fn clear(&mut self) -> Result<()>
