Member Function Documentation

◆ detectEdges()

virtual void cv::ximgproc::EdgeDrawing::detectEdges ( InputArray  src)
pure virtual
Python:
cv.ximgproc_EdgeDrawing.detectEdges(src) -> None

Detects edges and prepares them to detect lines and ellipses.

Parameters
srcinput image

◆ detectEllipses()

virtual void cv::ximgproc::EdgeDrawing::detectEllipses ( OutputArray  ellipses)
pure virtual
Python:
cv.ximgproc_EdgeDrawing.detectEllipses([, ellipses]) -> ellipses

Detects circles and ellipses.

Parameters
ellipsesoutput Vec<6d> contains center point and perimeter for circles.
Note
you should call detectEdges() method before call this.

◆ detectLines()

virtual void cv::ximgproc::EdgeDrawing::detectLines ( OutputArray  lines)
pure virtual
Python:
cv.ximgproc_EdgeDrawing.detectLines([, lines]) -> lines

Detects lines.

Parameters
linesoutput Vec<4f> contains start point and end point of detected lines.
Note
you should call detectEdges() method before call this.

◆ getEdgeImage()

virtual void cv::ximgproc::EdgeDrawing::getEdgeImage ( OutputArray  dst)
pure virtual
Python:
cv.ximgproc_EdgeDrawing.getEdgeImage([, dst]) -> dst

◆ getGradientImage()

virtual void cv::ximgproc::EdgeDrawing::getGradientImage ( OutputArray  dst)
pure virtual
Python:
cv.ximgproc_EdgeDrawing.getGradientImage([, dst]) -> dst

◆ getSegments()

virtual std::vector<std::vector<Point> > cv::ximgproc::EdgeDrawing::getSegments ( )
pure virtual
Python:
cv.ximgproc_EdgeDrawing.getSegments() -> retval

◆ setParams()

void cv::ximgproc::EdgeDrawing::setParams ( const EdgeDrawing::Params parameters)
Python:
cv.ximgproc_EdgeDrawing.setParams(parameters) -> None

sets parameters.

this function is meant to be used for parameter setting in other languages than c++.
