Matlab code.

Here is the smile file.

Here are the transformation matrices the problem talks about (3 matrices of size 4x4).

[1 0 0 4; 0 1 0 -5; 0 0 1 6; 0 0 0 1]

[1 0 0 0; 0 2 0 0; 0 0 3 0; 0 0 0 1]

[-1 0 0 4; 0 1 0 2; 0 0 1 0; 0 0 0 1]

2 Experiments 30% The image below consists of a large number of points with color, called "pixels". When we draw all these pixels, we see the image. Now we have a image of a "smile" and the following Matlab code draw all the pixels in 3D space to show the image. Can you modify the program to separately transform the image by the transformation matrices computed captured above? 1 clear all 2 close alI 3 clc 6 im double (imread(/smile.png )) s row.im column im] -size(im) 0 figure 1.5 set (gcf.
