What is circular Hough transform on Matlab?
The Hough transform may be used to detect circular shapes in images, after binarisation, for example by an edge detector. Often, functions to do this operation require the radius of the circle to be specified.
How to detect lines in an image matlab?
Find lines in the image using the houghlines function. lines = houghlines(BW,theta,rho,P,'FillGap',5,'MinLength',7); Create a plot that displays the original image with the lines superimposed on it. figure, imshow(rotI), hold on max_len = 0; for k = 1:length(lines) xy = [lines(k).
