Methods

	Name	Description
	Angle	Calculates angle orientation of a blob. This function uses central moments so cvCentralMoments should have been called before for this blob. (cvAngle)
	CalcCentroid	Calculates centroid. Centroid will be returned and stored in the blob structure. (cvCentroid)
	Clone
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	SaveImage	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	Set central/hu moments and centroid value from moment values (M**)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
