HoughLinesWorkflow

Requires Python3 with openCVClassical Hough Line: Detect lines in a binary imageNB : Good practice to skeletonize the image before, to avoid too many linesThe hough algorithm is an iterative line serach that iterates over angles and line spacing to find lines- Increment line spacing (Rho) : distance in pixels between consecutive paralell line search- Increment angle: step size in degrees for the search of lines (0-180°) for a given Rho- Min line length: Minimum number of points lying on a line to be returned by the algorythm Right clic to set parametersOpen ImagesSee lines overlaySobelThreshold Edge map HoughLines Image Reader InteractiveSegmentation View Sobel Global Thresholder Requires Python3 with openCVClassical Hough Line: Detect lines in a binary imageNB : Good practice to skeletonize the image before, to avoid too many linesThe hough algorithm is an iterative line serach that iterates over angles and line spacing to find lines- Increment line spacing (Rho) : distance in pixels between consecutive paralell line search- Increment angle: step size in degrees for the search of lines (0-180°) for a given Rho- Min line length: Minimum number of points lying on a line to be returned by the algorythm Right clic to set parametersOpen ImagesSee lines overlaySobelThreshold Edge map HoughLines Image Reader InteractiveSegmentation View Sobel Global Thresholder
