To run the programme,

1. Locate in the /code folder.
2. Execute 'init.m' to read all images into matrices. (Note: This could take some time)
3. Based on which exercise you want to look at, copy the corresponding paragraph well specified in 'ex_commands.m' and execute it.
   Alternatively, you can simply run 'ex_commands.m' and all the results should be presented in order.
4. Images will be written in the folder /results/jpg or /results/pgmppm.
   Of course you can empty all the images in there before executing 3).

a) Due to the inconsistence of requirements between the instructions in the document and on QMplus, as well as the file size limitation on the submission page, I removed most of the generated pgm/pgm files and the docx report from my submission (they take up too much space) and compressed my PDF report.
However, the compele set of my coursework can be found on my personal Github page. All rights reserved
b) Open any of these ppm/pgm files, there is a signature of my name embedded in the header (as required in the exercise).
c) In 'ex_commands.m' the statements for writing ppm/pgm files are commented, because they consume too much time.
You can un-comment them and execute if you wish.
