Hi! I have a problem with the function houghlines : it returns me an empty struct 1x1. Moreover : do you know how to transform the struct in a list of equations of the lines ?? Thank you very much
imm = [0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0, 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0, 0 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0, 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0, 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0, 0 0 0 0 1 1 0 0 0 1 1 1 0 0 0 0, 1 1 1 1 0 0 1 1 1 0 0 0 1 1 1 1, 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0, 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0, 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0, 0 0 0 0 0 0 1 1 1 1 1 0 0 0 0 0, 0 0 0 0 0 0 0 0 1 0 0 1 1 1 0 0, 0 0 0 0 0 0 0 1 0 0 0 0 0 0 1 1, 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0, 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0, 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0];
imshow (imm);
[H, THETA, RHO] = hough(imm);
picchi = houghpeaks(H,50
linee = houghlines(imm, THETA, RHO, picchi);
