WebI think one parameter that you need to tune is the 'FillGap' which will connect the very short segments. I tried: lines = houghlines (BW,T,R,P,'FillGap',30,'MinLength',15); And the image I obtained: There is still plenty of room for improvement, yet at least most lines are detected. Note that the theta-axis in hough peaks indicates the slopes ... WebThe variable rho is the distance from the origin to the line along a vector perpendicular to the line.theta is the angle between the x-axis and this vector. The hough function generates a parameter space matrix whose rows and columns correspond to these rho and theta values, respectively.. After you compute the Hough transform, you can use the houghpeaks …
