COMP6021 Colour Blind?

If you are colour blind you should probably let Colin know.

COMP6021 Assignment

Image compression requires a trade-off between image quality and file size. If the compression ratio is set too high the image quality becomes unacceptable. If it is set too low, bits are wasted. Finding the right point on the cost-quality curve can be a challenge.

Take three very different high resolution images of dimensions greater than 600 x 800 pixels.

For each image:

• Resize (or crop if you must) the image to size 600 x 800.
• Save the image with increasingly fewer colors, with and without dithering, until you believe you have found the best settings for the image.
• Demonstrate that pushing the compression ration further would produce poor results
• Graph the size of the image against the number of colors, with and without dithering on the same graph

Write a report outlining your results. The report should contain sample images.

I will bring images to the lab.

Put the report online and e-mail the URL to Colin before noon on Friday 05 November

CMOD6001 Project Groups & Blogs

Groups for the final project seem to have formed already.

Each student should join a group this week. Each group should start a blog (at blogger.com. I can help you with this the next time we are in a computer lab) to document the progress of the project and to store the minutes of each meeting. This blog should also reflect the individual contributions of each member.

E-mail the URL of the blog to Colin

CMOD6001 Class 14

The projector wouldn't talk to my laptop.

I asked student to form groups where no two students are writing the same paper topic, and asked each student to explain the background of the area to everyone else in the group.

Students must upload a first draft of the introduction to the paper to Turnitin by noon on Fri 22 October.

I gave out handouts on the comma.

I was impressed with the discussions students had. I feel like students have bought into this module and I appreciate it. It was a big ask.

SOFT6001 Exam in Week 06

We will have an in-class assessment on 21 October.

This will be an individual assessment, not a group exercise.

It will be worth 10/100 of your overall mark.

The in class group exercises that you do every week contribute 30/100. The remaining 60/100 comes from the exam at the end-ish if the semester.

So if you do well in it you will have almost passed the module.

If you have work commitments on that night and can't make the exam, please let me know and I will try to find an alternative plan for you.

SOFT6001 Week 05

All groups did very well on tonight's problem. I am very pleased.

I did feel though that not everybody had read the comments I posted on last week problem.

SOFT6001 Week 05 - tonight's problem

Tonight's problem is here is you are keen to make a start

COMP6021 Class 12

We looked at image sub-sampling, pixel resizing, and interpolation.

I thought today's class was especially dull, but maybe it was just me.

Homework:
A row of pure black pixels, is followed by a missing row, that is followed by pure red (R:255 G:255: B:255) pixels. If the missing row is interpolated what RGB values would you expect the missing pixels to have?

COMP6021 Class now full

CMOD6001 Class 12

I gave out handouts on note taking.

We discussed the marking of Assessment 1.

We talked about the project and decided on a Lip Dub video. We will discuss more about that in a later class.

Students researched their papers. I met with each student to discuss how they were getting on with the paper.

COMP6021 Class 11

Students worked on fax coding for the first half of the class.

We looked at digital color. HSB, RGB, Lab, CMYK

I gave students a color safari exercise.

COMP6021 Class 10

We looked at coding 1-bit images and fax machines.

Fax machines use run-length encoding, a modified Huffman code, and sometimes even a form of difference coding.

Deana the amazing human fax machine was the first to decode the image of the happy face
 with a goatee.

Homework:
Code an image on a 12x12 grid. Add it as a comment to the blog.

CMOD6001 Assessment 1 results available

I have completed grading student submissions for Assessment 1. Most student should be able to see their marks out of 10 by logging into turnitin again.

Each student's mark was based both on the student's ability to discuss the job in class and the student's submission to turnitin. The ability to discuss the job in class counted for a lot.

CMOD6001 Class 11

We completed our look at the jobs.

Students should upload their submission to TurnItIn over the weekend. By Monday it will be too late.

IF & Flowcharts

Problem:
Write a program that inputs three numbers and outputs the smallest of the three

Some solutions

COMP6021 Class 09

We discussed how perception in part reality, part biology, and part culture.

We saw the Gorilla video on YouTube. Some people don't even see the gorilla, but everyone in this claims claims that they did.

We looked at the physics of light, and the biology of vision. The I asked why there are 7 colours in the rainbow and argued that it is just because somebody made that up.

I fantasized about being the leader of North Korea and changing the way everybody names colours.

The way we think about color is very cultural. Irish has no word for pink. This interesting article from Wikipedia on the Japanese color 青  and this article on distinguishing blue from green across cultures make the same point quite well.

CMOD6001 Class 10

We talked a little bit about the free choice. I explained how pass by compensation works and discussed the appeals process.

The we looked at some more jobs.

I showed students a lip dub YouTube and asked if they were up to making one of their own as a project. No one seemed that convinced so we might do something more boring.
