Calculates coordinates of line segment corresponded by point in Hough space

line = cv.HoughPoint2Line(houghPoint, srcImgInfo)
line = cv.HoughPoint2Line(..., 'OptionName',optionValue, ...)

Input

• houghPoint Point in Hough space [x,y].
• srcImgInfo The source (input) image of Hough transform.

Output

• line Coordinates of line segment corresponded by point in Hough space, a 4-element integer vector [vx,vy, ux,uy].

Options

• AngleRange The part of Hough space where point is situated. See cv.FastHoughTransform, default ARO_315_135.
• MakeSkew Specifies to do or not to do image skewing. See cv.FastHoughTransform, default 'Deskew'.
• Rules Specifies strictness of line segment calculating. This specifies the degree of rules validation. This can be used, for example, to choose a proper way of input arguments validation. Default 'IgnoreBorders':
  • Strict Validate each rule in a proper way.
  • IgnoreBorders Skip validations of image borders.

The function calculates coordinates of line segment corresponded by point in Hough space.

Notes

• If Rules parameter set to 'Strict' then returned line cut along the border of source image.
• If Rules parameter set to 'IgnoreBorders' then in case of point, which belongs the incorrect part of Hough image, returned line will not intersect source image.
