Hough Line Transform — OpenCV Documentation - GitHub Pages

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. WebStandard Hough Line Transform. First, you apply the Transform: vector lines; HoughLines(dst, lines, 1, CV_PI/180, 100, 0, 0 ); with the following arguments: dst : Output of the edge detector. It should be a grayscale image (although in fact it is a binary one) lines : A vector that will store the parameters ( r, θ) of the detected lines. http://www.duoduokou.com/python/63086798895633149271.html tsl bastones
