Description
Abstract
Thank you for surviving the term. This assignment is a bonus, and should be the easiest
of them all. You simply need to use numpy.nanmean and numpy.nanmedian. You can
also try some other methods if you want, in making the image even look better. PLEASE
ALSO DO THIS ASAP. IT SHOULD ONLY TAKE 30 MIN TOPS.
Instructions are provided first for a reason.
Please read the instructions carefully.

1 Instructions
1.1 Submission package
Within the homework assignment package, there should be a submission-package.zip,
which contains the directory structure and empty files for you to get started. Please edit
the contents within the file for code, and then create a zip archive with the file name
submission-package.zip, and submit it. Do not use other archive formats such
as rar or tar.gz.
All assignments should be submitted electronically. Hand written reports are not accepted. You can, however, include scanned pages in your report. For example, if you are not
comfortable with writing equations, you can include a scanned copy.
1.2 Code
All assignments should be in Python 3. Codes that fail to run on Python 3 will receive 20%
deduction on the final score. In other words, do not use Python 2.7.
For this assignment, you should not need to create additional files. Fill in the skeleton
files in the submission package. Do not change the name of these scripts. Your code should
run as specified by the assignment specs by simply doing
python solution.py
in the command line. Do not expect additional command line arguments as input.
It is strongly encouraged to follow PEP8. It makes your code much more readable, and
less room for mistakes. There are many open source tools available to automatically do this
for you.
1.3 Delayed submission
In case you think you will not meet the deadline due to network speed or any other reasons,
you can send an email with the SHA-256 hash of your .zip archive first, and then submit
your assignment through email later on. This will not be considered as a delay.
Delayed submissions are subject to 20% degradation per day. For example, an assignment
submitted 1 minute after the deadline will receive 80% of the entire mark, even if it was
perfect. Likewise, an assignment that was submitted one day and 1 minute after the deadline
will receive 60%.
1.4 Use of open source code
Any library under any type of open source license is allowed for use, given full attribution.
This attribution should include the name of the original author, the source from which the
code was obtained, and indicate terms of the license. Note that using copyrighted material
without an appropriate license is not permitted. Short snippets of code on public websites
such as StackOverflow may be used without an explicit license, but proper attribution should
be given even in such case. This means that if you embed a snippet into your own code,
you should properly cite it through the comments, and also embed the full citation in a
LICENSES file. However, if you include a full, unmodified source, which already contains the
license within the source file, this is unnecessary. Please note that without proper attribution,
it will be considered plagiarism.

In addition, as the assignments are intended for you to learn, (1) if the external code
implements the core objective of the task, no points will be given; (2) code from other
CSC205 students will count as plagiarism.
2 Aggregating multiple images to remove artifacts
(2 marks)
Implement solution.py, specifically the TODO parts in merge images. You only have to
use np.nanmean and np.nanmedian to do each task. You can also test to run the mean
version by doing python solution.py –method mean.
Here are some example outputs that opencv should give you. Simply press a key to keep
on running the stitching process.
