boofcv.alg.shapes.ellipse.EdgeIntensityEllipse<T>

public class EdgeIntensityEllipse<T extends boofcv.struct.image.ImageGray>
extends BaseIntegralEdge<T>

Computes the edge intensity along the an ellipse.

Edge Intensity Definition:
The average difference in pixel values. Maximum value is (max pixel val - min pixel val).

Constructor Detail

EdgeIntensityEllipse

public EdgeIntensityEllipse(double tangentDistance,
                            int numContourPoints,
                            double passThreshold,
                            java.lang.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 Detail

process

public boolean process(georegression.struct.shapes.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
