CWIMAQCurveOptions

CWIMAQCurveOptions contains parameters used by various methods to find curves in an image.

Properties

ColumnStepSizeSpecifies the distance, in the x direction, between columns of pixels in the image that the method inspects for curve seed points.
ExtractionModeSpecifies how the method identifies curves in the image.
FilterSizeSpecifies the width of the edge filter the method uses to identify curves in the image.
MaxEndPointGapSpecifies the maximum gap, in pixels, between the endpoints of a curve that the function identifies as a closed curve.
MinLengthSpecifies the length, in pixels, of the smallest curve the method will extract.
OnlyClosedSpecifies whether the method identifies only closed curves in the image.
RowStepSizeSpecifies the distance, in the y direction, between lines that the method inspects for curve seed points.
SubPixelAccuracySpecifies whether the method identifies the location of curves with subpixel accuracy by interpolating between points to find the crossing of the threshold.
ThresholdSpecifies the minimum contrast a seed point must have for the method to begin a curve.
