Parameters

Name	Type	Default	Description
stRoiSize	TcVnSize2_DINT	(.nWidth := 416, .nHeight := 416)	Desired ROI dimensions in original-image pixels.
fMinDensity	LREAL	0.2	Minimum feature density required to keep an ROI, given as a factor of the image's average density. Higher values keep fewer ROIs; suggested range [0.0, 2.0]. 0.0 disables the filter.
fDetectionScaleFactor	LREAL	0.25	Scale factor that controls the resolution of the ROI detection (Lower = faster density evaluation; valid range [0.1, 1.0]).
fMaxOversizeFraction	LREAL	1.0	Fraction by which ROIs may exceed stRoiSize (required only when eFindRoisMethod = TCVN_FRM_CONNECTEDCOMPONENTS).
