static

detectEdges()

void OpenCVForUnity.XimgprocModule.EdgeDrawing.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.

detectEllipses()

void OpenCVForUnity.XimgprocModule.EdgeDrawing.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.

detectLines()

void OpenCVForUnity.XimgprocModule.EdgeDrawing.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.

Dispose()

override void OpenCVForUnity.XimgprocModule.EdgeDrawing.Dispose ( bool  disposing )

protectedvirtual

Reimplemented from OpenCVForUnity.CoreModule.Algorithm.

getEdgeImage()

void OpenCVForUnity.XimgprocModule.EdgeDrawing.getEdgeImage

(

Mat

dst

)

returns Edge Image prepared by detectEdges() function.

Parameters

dst	returns 8-bit, single-channel output image.

getGradientImage()

void OpenCVForUnity.XimgprocModule.EdgeDrawing.getGradientImage

(

Mat

dst

)

returns Gradient Image prepared by detectEdges() function.

Parameters

dst	returns 16-bit, single-channel output image.

getSegmentIndicesOfLines()

MatOfInt OpenCVForUnity.XimgprocModule.EdgeDrawing.getSegmentIndicesOfLines

(

)

Returns for each line found in detectLines() its edge segment index in getSegments()

getSegments()

List<MatOfPoint> OpenCVForUnity.XimgprocModule.EdgeDrawing.getSegments

(

)

Returns std::vector<std::vector<Point>> of detected edge segments, see detectEdges()

setParams()

void OpenCVForUnity.XimgprocModule.EdgeDrawing.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
