Method Detail

__fromPtr__

public static BOWKMeansTrainer __fromPtr__(long addr)

cluster

public Mat cluster()

Overrides:

cluster in class BOWTrainer

cluster

public Mat cluster(Mat descriptors)

Description copied from class: BOWTrainer

Clusters train descriptors.

Overrides:

cluster in class BOWTrainer

Parameters:

descriptors - Descriptors to cluster. Each row of the descriptors matrix is a descriptor. Descriptors are not added to the inner train descriptor set. The vocabulary consists of cluster centers. So, this method returns the vocabulary. In the first variant of the method, train descriptors stored in the object are clustered. In the second variant, input descriptors are clustered.

Returns:

automatically generated
