Web8 de jan. de 2011 · OpenCV implementation is based on Robust Detection of Lines Using the Progressive Probabilistic Hough Transform by Matas, J. and Galambos, C. and Kittler, J.V.. The function used is cv2.HoughLinesP (). It has two new arguments. minLineLength - Minimum length of line. Line segments shorter than this are rejected. 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. how to see tables in microsoft word
