surface mapping image in matlab

To surface map an image in Matlab, you can use the surf function.

Here's an example code:

main.m
% read the image and convert it to grayscale
I = imread('example_image.jpg');
Igray = rgb2gray(I);

% create a meshgrid for the x, y coordinates
[x, y] = meshgrid(1:size(Igray,2), 1:size(Igray,1));

% use the surf function to create a 3D mesh and map the image onto it
surf(x, y, zeros(size(Igray)), double(Igray)/255, 'edgecolor', 'none');
view(2);
colormap(gray);
axis image;

This code reads in an example image and converts it to grayscale using the rgb2gray function. Then, it creates a meshgrid for the x and y coordinates and uses the surf function to create a 3D mesh with zero elevation and maps the grayscale values of the image onto it. Finally, it sets the view, colormap, and axis properties to display the resulting surface map.
