EdgeIntensityEllipse

public EdgeIntensityEllipse(double tangentDistance,
 int numContourPoints,
 double passThreshold,
 Class<T> imageType)

Configures edge intensity calculation

Parameters:

tangentDistance - Distance along tangent it will integrate

numContourPoints - Number of points along the contour it will sample. If ≤ 0 the test will always pass

passThreshold - Threshold for passing. Value: 0 to (max - min) pixel value.

imageType - Type of input image

Method Details

process

public boolean process(EllipseRotated_F64 ellipse)

Processes the edge along the ellipse and determines if the edge intensity is strong enough to pass or not

Parameters:

ellipse - The ellipse in undistorted image coordinates.

Returns:

true if it passes or false if not

getEdgeIntensity

public double getEdgeIntensity()
