IplImage.SnakeImage Method (CvPoint[], Single, Single, Single, CvSize, CvTermCriteria, Boolean)

IplImageSnakeImage Method (CvPoint, Single, Single, Single, CvSize, CvTermCriteria, Boolean)

OpenCvSharp Class Library

Changes contour position to minimize its energy

Namespace: OpenCvSharp
Assembly: OpenCvSharp (in OpenCvSharp.dll) Version: 1.0.0.0 (1.0.0.0)

Syntax

public void SnakeImage(
	CvPoint[] points,
	float alpha,
	float beta,
	float gamma,
	CvSize win,
	CvTermCriteria criteria,
	bool calcGradient
)

Public Sub SnakeImage ( 
	points As CvPoint(),
	alpha As Single,
	beta As Single,
	gamma As Single,
	win As CvSize,
	criteria As CvTermCriteria,
	calcGradient As Boolean
)

public:
void SnakeImage(
	array<CvPoint>^ points, 
	float alpha, 
	float beta, 
	float gamma, 
	CvSize win, 
	CvTermCriteria criteria, 
	bool calcGradient
)

member SnakeImage : 
        points : CvPoint[] * 
        alpha : float32 * 
        beta : float32 * 
        gamma : float32 * 
        win : CvSize * 
        criteria : CvTermCriteria * 
        calcGradient : bool -> unit

Parameters

points: Type: OpenCvSharpCvPoint
Contour points (snake).
alpha: Type: SystemSingle
Weight of continuity energy, single float or array of length floats, one per each contour point.
beta: Type: SystemSingle
Weight of curvature energy, similar to alpha.
gamma: Type: SystemSingle
Weight of image energy, similar to alpha.
win: Type: OpenCvSharpCvSize
Size of neighborhood of every point used to search the minimum, both win.width and win.height must be odd.
criteria: Type: OpenCvSharpCvTermCriteria
Termination criteria.
calcGradient: Type: SystemBoolean
Gradient flag. If true, the function calculates gradient magnitude for every image pixel and consideres it as the energy field, otherwise the input image itself is considered.
