WebWorking of Hough Transform in OpenCV Simple shapes like lines, circles etc. in a given image can be detected using a feature extraction method called hough transform. The lines in a given image can be detected using HoughLines () function and HoughLinesP () function. Detection of lines in a given image works by first initializing the accumulator. Webcv.HoughLinesPointSet 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.
