Detailed Description

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. :

Member Function Documentation

◆ __fromPtr__()

static BOWTrainer OpenCVForUnity.Features2dModule.BOWTrainer.__fromPtr__ ( IntPtr addr)
static

◆ add()

void OpenCVForUnity.Features2dModule.BOWTrainer.add ( Mat descriptors)

Adds descriptors to a training set.

Parameters
descriptorsDescriptors 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.

◆ clear()

void OpenCVForUnity.Features2dModule.BOWTrainer.clear ( )

◆ cluster() [1/2]

virtual Mat OpenCVForUnity.Features2dModule.BOWTrainer.cluster ( )
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.

◆ cluster() [2/2]

virtual Mat OpenCVForUnity.Features2dModule.BOWTrainer.cluster ( Mat descriptors)
virtual

Clusters train descriptors.

Parameters
descriptorsDescriptors 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.

◆ descriptorsCount()

int OpenCVForUnity.Features2dModule.BOWTrainer.descriptorsCount ( )

Returns the count of all descriptors stored in the training set.

◆ Dispose()

override void OpenCVForUnity.Features2dModule.BOWTrainer.Dispose ( bool disposing)
protectedvirtual

Reimplemented from OpenCVForUnity.DisposableObject.

◆ getDescriptors()

List< Mat > OpenCVForUnity.Features2dModule.BOWTrainer.getDescriptors ( )

Returns a training set of descriptors.

◆ getNativeObjAddr()

IntPtr OpenCVForUnity.Features2dModule.BOWTrainer.getNativeObjAddr ( )
