ImageLocalExtremaVerification

Description

This structure contains parameters for verification of local extrema visible on an image.

Structure fields and default values (if defined) are described below:

• int PointCount = 8 - Defines how many of pixel values along verification circle will be checked in order to compute extremum strength
• float Radius = 3.0f - Defines radius of verification circle
• float MinDifference = 0.0f - Defines minimal difference between a local extremum pixel value and verification circle pixels

	int		PointCount;
	float	Radius;
	float	MinDifference;

	explicit ImageLocalExtremaVerification

		int PointCount_ = 8,

		 MinDifference(MinDifference_)
