        public static EdgeDrawing __fromPtr__​(long addr)

      • detectEdges

        public void detectEdges​(Mat src)
        Detects edges in a grayscale image and prepares them to detect lines and ellipses.
        Parameters:
        src - 8-bit, single-channel, grayscale input image.

      • getEdgeImage

        public void getEdgeImage​(Mat dst)
        returns Edge Image prepared by detectEdges() function.
        Parameters:
        dst - returns 8-bit, single-channel output image.

      • getGradientImage

        public void getGradientImage​(Mat dst)
        returns Gradient Image prepared by detectEdges() function.
        Parameters:
        dst - returns 16-bit, single-channel output image.

      • getSegments

        public java.util.List<MatOfPoint> getSegments()
        Returns std::vector<std::vector<Point>> of detected edge segments, see detectEdges()
        Returns:
        automatically generated

      • getSegmentIndicesOfLines

        public MatOfInt getSegmentIndicesOfLines()
        Returns for each line found in detectLines() its edge segment index in getSegments()
        Returns:
        automatically generated

      • detectLines

        public void detectLines​(Mat lines)
        Detects lines.
        Parameters:
        lines - output Vec<4f> contains the start point and the end point of detected lines. Note: you should call detectEdges() before calling this function.

      • detectEllipses

        public void detectEllipses​(Mat ellipses)
        Detects circles and ellipses.
        Parameters:
        ellipses - output Vec<6d> contains center point and perimeter for circles, center point, axes and angle for ellipses. Note: you should call detectEdges() before calling this function.

      • setParams

        public void setParams​(EdgeDrawing_Params parameters)
        sets parameters. this function is meant to be used for parameter setting in other languages than c++ like python.
        Parameters:
        parameters - Parameters of the algorithm

        protected void finalize()
                 throws java.lang.Throwable
        Overrides:
        finalize in class Algorithm
        Throws:
        java.lang.Throwable
