cvGoodFeaturesToTrack

Determines strong corners on an image.

	Name	Type	Range	Description
	inImage	Image		Input single-channel UINT8 or REAL image.
	inMaxCorners	Integer	0 -	Maximum number of corners to return. If there are more corners than are found, the strongest of them is returned.
	inQualityLevel	Real	0.0 - 1.0	Parameter characterizing the minimal accepted quality of image corners.
	inMinDistance	Real	0.0 -	Minimum possible Euclidean distance between the returned corners.
	inMask	Region *		Region of interest.
	inBlockSize	Integer	1 -	Size of an average block for computing a derivative covariation matrix over each pixel neighborhood.
	inUseHarrisDetector	Bool		Parameter indicating whether to use a Harris detector or cornerMinEigenVal.
	inK	Real		Free parameter of the Harris detector.
	outCorners	Point2D Array		Output array of detected corners.
