Detailed Description

Collection of class information inside a classification sample list.

Member Function Documentation

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

inline

Add a sample to a new class. If the class indicated by the label already exists the sample will be added to the existing class.

Parameters

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

Parameters

[in] mode Interpretation hint for the extractionLocation parameter.

Exceptions

Any	exception derived from std::exception including CvbException.

bool HasLabel ( const String & label )

inline

Check if a given label is already present in the classes collection.

Parameters

[in] label Label to test for.

Returns: True if a class with the specified label already exists, false otherwise.

Exceptions

Any	exception derived from std::exception including CvbException.
