EdgeScanParams

Description

This structure contains parameters of edge scanning process. Instance of this structure should be customized and passed as a parameter to edge scanning related functions.

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

• ProfileInterpolationMethod ProfileInterpolation = Quadratic4 - Selects the method of sub-pixel precise edge detection
• float SmoothingStdDev = 0.6f - Parameter for gaussian smoothing of the brightness profile
• float MinMagnitude = 5.0f - Minimum acceptable edge strength
• EdgeTransition EdgeTransition - Specifies the type of edges to be detected

	ProfileInterpolationMethod	ProfileInterpolation;
