Member Function Documentation

Add()

void Add ( const Image &  srcImage, Point2D< int >  extractionLocation, SampleExtractionMode  mode = SampleExtractionMode::TopLeftCorner  )

inline

Add a new sample to an existing class.

Parameters

[in]	srcImage	Image from which to extract the sample for the class.
[in]	extractionLocation	Location at which to extract the sample for the class. Note that what the extraction location actually refers dependent on the value of the mode parameter.
[in]	mode	Interpretation hint for the extractionLocation parameter.

Exceptions

Any	exception derived from std::exception including CvbException.

Index()

int Index ( ) const

inline

Get the index of this label.

Returns

The label index.

Exceptions

Any	exception derived from std::exception including CvbException.

Note that this index may change when samples are removed from the image list - therefore you should check this index often. Generally it is more recommendable to work label based, not index based.

Label()

std::vector<float> Label ( ) const

inline

Get label under which this class is stored.

Returns

The label.

Exceptions

Any	exception derived from std::exception including CvbException.

You may change this label, but not to one that already exists in the SampleList. To Merge labels in the SampleList use the merge method(s) of the sample list.

Relabel()

void Relabel ( const std::vector< float > &  label )

inline

Modify the label of a sample set, but not to one that already exists in the sample list.

Parameters

[in]

label

The new label.

Exceptions

Any	exception derived from std::exception including CvbException.

To merge labels in the list use the merge method of the ImageClassificationInfoCollection.

Samples()

ImageCollection Samples ( ) const

inline

Get samples under this label.

Returns

The samples.

Exceptions

Any	exception derived from std::exception including CvbException.
