Assignment 1 (Denoising Images)
What to do: You will apply 5 algorithms on the 4
images corrupted by different types of noises. Image01.jpg was corrupted by Poisson noise. Image02.jpg was corrupted by Gaussian noise. Image03.jpg was corrupted by speckle noise and Image04.jpg was corrupted by salt and pepper noise.

What are these 5 algorithms? You should choose (a) one linear filter,
(b) two non-linear filters, and (c) two algorithms based on deep neural
networks. You are not required to write any code for this assignment. You will
use existing codes from the publicly available domain. Cite the sources (such
as papers and/or software sites).
What to submit?
20 denoised images, name them as
image1_alg1.jpg, image1_alg2.jpg, ..., image4_alg5.jpg.
Also, write a report with (1) the short
descriptions of five algorithms you have chosen with citations of their sources
and citations of codes you used and (2) noisy images and their denoised
versions obtained with each algorithm and your observations about these
results. Your report length should not exceed 5 pages formatted as
single-spaced, single column, using 12pt font text. I encourage you to use
latex. Overleaf is a great free service you can make use of.
Marking: I have the original images. I will
numerically compare your submitted denoised images against the original images.
I will use SSIM metric (https://en.wikipedia.org/wiki/Structural_similarity)
for this purpose. I will use the average SSIM score in the formula: 60 + (your
average SSIM for 20 images)*40 to compute your score for this part of the
assignment This score will have 4% of the total 10% allocated for the
assignment.
Another 6% will be
devoted to your (maximum) 5-page report.
zip all files into a single file and name as
firstname_lastname.zip and submit.
