Hello Guys, I'm a newbie in MATLAB and then I have some project. Here are some pictures I transform into a 3D graphic. The result is full of noise. I read there are some filtering images like Gaussian, Laplace, Canny, Sobel etc. But how I can apply them to my picture so it's become better to transform into the 3D plot.
% I use this code to make the 3D plot
a = imread('edge_final.jpg');
b = rgb2gray (a);
surf(b,'EdgeColor','none')
colorbar;
colormap(jet(50));
