Method Detect

Namespace

OpenCvSharp.XImgProc

Assembly

OpenCvSharp.dll

Detect(InputArray, OutputArray)

Finds lines in the input image. This is the output of the default parameters of the algorithm on the above shown image.

public virtual void Detect(InputArray image, OutputArray lines)

Parameters

image InputArray

A grayscale (CV_8UC1) input image. If only a roi needs to be selected, use: fld_ptr-\>detect(image(roi), lines, ...); lines += Scalar(roi.x, roi.y, roi.x, roi.y);

lines OutputArray

A vector of Vec4f elements specifying the beginning and ending point of a line. Where Vec4f is (x1, y1, x2, y2), point 1 is the start, point 2 - end.Returned lines are directed so that the brighter side is on their left.

Detect(InputArray)

Finds lines in the input image. This is the output of the default parameters of the algorithm on the above shown image.

public virtual Vec4f[] Detect(InputArray image)

Parameters

image InputArray

A grayscale (CV_8UC1) input image. If only a roi needs to be selected, use: fld_ptr-\>detect(image(roi), lines, ...); lines += Scalar(roi.x, roi.y, roi.x, roi.y);

Returns

Vec4f[]

A vector of Vec4f elements specifying the beginning and ending point of a line. Where Vec4f is (x1, y1, x2, y2), point 1 is the start, point 2 - end.Returned lines are directed so that the brighter side is on their left.
