CvArr.LogPolar Method (CvArr, CvPoint2D32f, Double, Interpolation)

CvArrLogPolar Method (CvArr, CvPoint2D32f, Double, Interpolation)

OpenCvSharp Class Library

Remaps image to log-polar space. The function emulates the human "foveal" vision and can be used for fast scale and rotation-invariant template matching, for object tracking etc.

Copy

public void LogPolar(
	CvArr dst,
	CvPoint2D32f center,
	double m,
	Interpolation flags
)

Public Sub LogPolar ( 
	dst As CvArr,
	center As CvPoint2D32f,
	m As Double,
	flags As Interpolation
)

public:
void LogPolar(
	CvArr^ dst, 
	CvPoint2D32f center, 
	double m, 
	Interpolation flags
)

member LogPolar : 
        dst : CvArr * 
        center : CvPoint2D32f * 
        m : float * 
        flags : Interpolation -> unit

Parameters

dst: Type: OpenCvSharpCvArr
Destination image.
center: Type: OpenCvSharpCvPoint2D32f
The transformation center, where the output precision is maximal.
m: Type: SystemDouble
Magnitude scale parameter. See below.
flags: Type: OpenCvSharpInterpolation
A combination of interpolation method and the optional flags.
