OpenCV: Hough Line Transform

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.
