C# Class OpenCvSharp.Blob.CvBlob

显示文件 Open project: shimat/opencvsharp Class Usage Examples

Public Methods

Method	Description
Angle ( ) : double	Calculates angle orientation of a blob. This function uses central moments so cvCentralMoments should have been called before for this blob. (cvAngle)
CalcCentroid ( ) : Point2d	Calculates centroid. Centroid will be returned and stored in the blob structure. (cvCentroid)
Clone ( ) : CvBlob
CvBlob ( ) : System	Constructor
SaveImage ( string fileName, Mat img ) : void	Save the image of a blob to a file. The function uses an image (that can be the original pre-processed image or a processed one, or even the result of cvRenderBlobs, for example) and a blob structure. Then the function saves a copy of the part of the image where the blob is.
SetMoments ( ) : void	Set central/hu moments and centroid value from moment values (M**)

Method Details

Angle() public method

Calculates angle orientation of a blob. This function uses central moments so cvCentralMoments should have been called before for this blob. (cvAngle)

public Angle ( ) : double
return	double

CalcCentroid() public method

Calculates centroid. Centroid will be returned and stored in the blob structure. (cvCentroid)

public CalcCentroid ( ) : Point2d
return	Point2d

Clone() public method

public Clone ( ) : CvBlob
return	CvBlob

CvBlob() public method

Constructor

public CvBlob ( ) : System
return	System

SaveImage() public method

Save the image of a blob to a file. The function uses an image (that can be the original pre-processed image or a processed one, or even the result of cvRenderBlobs, for example) and a blob structure. Then the function saves a copy of the part of the image where the blob is.

public SaveImage ( string fileName, Mat img ) : void
fileName	string	Name of the file.
img	Mat	Image.
return	void

SetMoments() public method

Set central/hu moments and centroid value from moment values (M**)

public SetMoments ( ) : void
return	void
