Question

求能够运行的用matlab进行hough变换直线检测的程序。急！

类似：http://hi.baidu.com/hpc%5Frobot/blog/item/82f851ec61fbdd2f63d09f7e.html
里面的程序。
可加分啊！

Answer 1

直接运行：

RGB = imread('gantrycrane.png');
I = rgb2gray(RGB); % convert to intensity
BW = edge(I,'canny'); % extract edges
[H,T,R] = hough(BW,'RhoResolution',0.5,'ThetaResolution',0.5);

% display the original image
subplot(2,1,1);
imshow(RGB);
title('gantrycrane.png');

% display the hough matrix
subplot(2,1,2);
imshow(imadjust(mat2gray(H)),'XData',T,'YData',R,...
'InitialMagnification','fit');
title('Hough transform of gantrycrane.png');
xlabel('\theta'), ylabel('\rho');
axis on, axis normal, hold on;
colormap(hot);
