Syntax

C#
public static void cvCalcEigenObjects(
	IntPtr[] input,
	ref MCvTermCriteria calcLimit,
	IntPtr[] eigVecs,
	float[] eigVals,
	IntPtr avg
)
Visual Basic (Declaration)
Public Shared Sub cvCalcEigenObjects ( _
	input As IntPtr(), _
	ByRef calcLimit As MCvTermCriteria, _
	eigVecs As IntPtr(), _
	eigVals As Single(), _
	avg As IntPtr _
)
Visual C++
public:
static void cvCalcEigenObjects(
	array<IntPtr>^ input, 
	MCvTermCriteria% calcLimit, 
	array<IntPtr>^ eigVecs, 
	array<float>^ eigVals, 
	IntPtr avg
)

Parameters

input
Type: array< System..::.IntPtr >[]()[]
Pointer to the array of IplImage input objects
calcLimit
Type: Emgu.CV.Structure..::.MCvTermCriteria %
Criteria that determine when to stop calculation of eigen objects. Depending on the parameter calcLimit, calculations are finished either after first calcLimit.max_iter dominating eigen objects are retrieved or if the ratio of the current eigenvalue to the largest eigenvalue comes down to calcLimit.epsilon threshold. The value calcLimit -> type must be CV_TERMCRIT_NUMB, CV_TERMCRIT_EPS, or CV_TERMCRIT_NUMB | CV_TERMCRIT_EPS . The function returns the real values calcLimit->max_iter and calcLimit->epsilon
eigVecs
Type: array< System..::.IntPtr >[]()[]
Pointer either to the array of eigen objects
eigVals
Type: array< System..::.Single >[]()[]
Pointer to the eigenvalues array in the descending order; may be NULL
avg
Type: System..::.IntPtr
Averaged object

Return Value

Pointer either to the array of eigen objects or to the write callback function
