Finds lines in a set of points using the standard Hough transform

lines = cv.HoughLinesPointSet(points)
lines = cv.HoughLinesPointSet(points, 'OptionName',optionValue, ...)

Input

• points Input vector of points {[x,y], ...}, floating-point type.

Output

• lines Output cell-array of found lines. Each line is encoded as a 3-element vector [votes, rho, theta]. The larger the value of votes, the higher the reliability of the Hough line.

Options

• LinesMax Max count of hough lines. default 200
• Threshold Accumulator threshold parameter. Only those lines are returned that get enough votes (> Threshold). default 10
• RhoMin Minimum Distance value of the accumulator in pixels. default 0
• RhoMax Maximum Distance value of the accumulator in pixels. default 100
• RhoStep Distance resolution of the accumulator in pixels. default 1
• ThetaMin Minimum angle value of the accumulator in radians. default 0
• ThetaMax Maximum angle value of the accumulator in radians. default pi/2
• ThetaStep Angle resolution of the accumulator in radians. default pi/180

The function finds lines in a set of points using a modification of the Hough transform.
