public class SnapToEllipseEdge<T extends ImageGray<T>>
extends BaseIntegralEdge<T>
Refines an initial estimate of an elipse using a subpixel contour technique. A local line integral around each point is used to determine how important each point is. The contour being

      public SnapToEllipseEdge​(int numSampleContour, int radialSamples, Class<T> imageType)
      Constructor with configuration
      Parameters:
      numSampleContour - Maximum number of iterations it will performance
      radialSamples - When the difference between two ellipses is less than this amount stop iterating
      imageType - Type of gray-scale input image

    • process

      public boolean process​(EllipseRotated_F64 input, EllipseRotated_F64 refined)
      Refines provided list by snapping it to edges found in the image
      Parameters:
      input - (Output) Close approximation of the ellipse in the image
      refined - (Output) Storage for refined estimate. Can be same instance as input
      Returns:
      True if a refined estimate could be found, false if it failed
