Public Member Functions
unsafe void	Add (float[] label, Image srcImage, Point2D extractionLocation, SampleExtractionMode mode=SampleExtractionMode.TopLeftCorner)
	Add a sample under a new value. If the value indicated by the label already exists the sample will be added to the existing label.
bool	HasValue (float[] value)
	Check if a given value is already present in the values collection.
void	Remove (float[] label)
	Remove all samples for a specific label.
void	MergeClasses (float[] fromLabel, float[] toLabel)
	Merge two classes into one class. The class label will be taken from the 2nd class index. Note that this operation will invalidate all indices higher than fromLabel .

Member Function Documentation

Add()

unsafe void Add	(	float[]	label,
		Image	srcImage,
		Point2D	extractionLocation,
		SampleExtractionMode	mode = SampleExtractionMode::TopLeftCorner )

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

Parameters

label	label of the new class.
srcImage	Image from which to extract the first sample for the new class.
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.
mode	Interpretation hint for the extractionLocation parameter.

Exceptions

ObjectDisposedException

If the image list has already been disposed.

GetInfo()

override ImageRegressionLabelInfo GetInfo ( int index )

protected

Parent class calls this method to extract one info object by index.

Parameters

index

index at which to extract

Returns

extracted object

Exceptions

ObjectDisposedException	If the SampleImageList has already been disposed
ArgumentOutOfRangeException	If the index is invalid

HasValue()

bool HasValue

(

float[]

value

)

Check if a given value is already present in the values collection.

Parameters

value

Value to test for.

Returns

True if an entry with the specified value already exists; false otherwise.

MergeClasses()

void MergeClasses	(	float[]	fromLabel,
		float[]	toLabel )

Merge two classes into one class. The class label will be taken from the 2nd class index. Note that this operation will invalidate all indices higher than fromLabel .

Parameters

fromLabel	Class to merge to the other classes.
toLabel	Class to merge the samples to.

Remove()

void Remove

(

float[]

label

)

Remove all samples for a specific label.

Parameters

label

label to be removed from the data base

Property Documentation

label

Parameters

label

Label to access

Returns
