cvCamShift Method (probImage, window, criteria, comp, box)

www.emgu.com/wiki

Implements CAMSHIFT object tracking algrorithm ([Bradski98]). First, it finds an object center using cvMeanShift and, after that, calculates the object size and orientation.

Declaration Syntax

Visual Basic

Visual C++

public static int cvCamShift(
	IntPtr probImage,
	MCvRect window,
	MCvTermCriteria criteria,
	out MCvConnectedComp comp,
	out MCvBox2D box
)

Public Shared Function cvCamShift ( _
	probImage As IntPtr, _
	window As MCvRect, _
	criteria As MCvTermCriteria, _
	<OutAttribute> ByRef comp As MCvConnectedComp, _
	<OutAttribute> ByRef box As MCvBox2D _
) As Integer

public:
static int cvCamShift(
	IntPtr probImage, 
	MCvRect window, 
	MCvTermCriteria criteria, 
	[OutAttribute] MCvConnectedComp% comp, 
	[OutAttribute] MCvBox2D% box
)

Parameters

probImage (IntPtr): Back projection of object histogram

window (MCvRect): Initial search window

criteria (MCvTermCriteria): Criteria applied to determine when the window search should be finished

comp ( MCvConnectedComp %): Resultant structure that contains converged search window coordinates (comp->rect field) and sum of all pixels inside the window (comp->area field).

box ( MCvBox2D %): Circumscribed box for the object. If not NULL, contains object size and orientation

Return Value

number of iterations made within cvMeanShift
