Homework 0 - Scale up an image using interpolation

Ordinary HW:

Create a MATLAB function which takes one argument:

1. Path to an image, e.g., "c:\\smiley.bmp"

and triple the size of the image and display it. Use nearest neighbor interpolation. 

Note: You can convert the image to a grayscale one in order not to deal with a 3D matrix. You are not allowed to use off-the-shelf MATLAB functions for zooming. The point of the HW is to implement a zooming and interpolation method. You can use MATLAB functions for other purposes, e.g., I = imread("c:\\smiley.bmp");

Bonus +50%:

via GIPHY

To make the function support any zoom amount, make the function take two arguments, one is the path as in ordinary HW, the other one is:

     2.  An integer indicating the desired amount of zoom, e.g., 5

And use bilinear interpolation.

Bonus + Lefting the lecturer speechless:

Do all the above and also support zooming in fractions, e.g., zoom: 3.42.

Good luck,

Kasım
