Programming Assignment: PCA

Total points: 100
Note: This assignment is for each individual student to complete on his or her
own.
In this assignment, you will implement PCA to compress images. To get started,
you will need to download the starter code and unzip its contents to the directory
where you wish to complete the assignment.
The problem considered in this assignment is to compress the image downloaded
from https://leafyplace.com/types-of-birds/
You are required the complete the following steps:
1. Implement the PCA to reduce the dimension of the data.
2. Construct the compressed image.

modify this script as well as all the other three scripts, including
• findPCs.m – Function to find the principle components
• PCAtransform.m – Function to transform data into the PC space
• PCAtransform_inv.m – Function to transform data back to the
original space
