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

void OpenCVForUnity.Features2dModule.BOWTrainer.add | ( | Mat | descriptors | ) |
Adds descriptors to a training set.
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.
void OpenCVForUnity.Features2dModule.BOWTrainer.clear | ( | ) |
|
virtual |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Reimplemented in OpenCVForUnity.Features2dModule.BOWKMeansTrainer.
Clusters train descriptors.
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.
Reimplemented in OpenCVForUnity.Features2dModule.BOWKMeansTrainer.
int OpenCVForUnity.Features2dModule.BOWTrainer.descriptorsCount | ( | ) |
Returns the count of all descriptors stored in the training set.
