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

This class is now full. No more students will be permitted to register.

If you wanted to take this class and missed out please e-mail me and I will let you know when it is next offered.

CMOD6001 Class canceled 2010-11-17

There will be no CMOD6001 class on 17 November.

COMP6021 Class Canceled 2010-11-17

There will be no COMP6021 class on Nov 17

CMOD6001 Class 13

I asked student to think about cyber etiquette and to come up with a list of recommendations that could server as a guide.

One group still has to send me a list.

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.

SOFT6001 Week 04

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.

CMOD6001 Class 09

We looked at some of the job specifications from earlier in the semester. Some students have not completed this task to my satisfaction.


I randomly distributed  topics for the upcoming writing exercise. More on that in future classes.

COMP6021 Class 08

We looked at how Blanck & White images can be digitized.

main themes:

• Sample rate - dots per inch
• Quantization levels - pixel depth

We saw examples of the same image with different sample rates and different quantization levels

Students used Photoshop to alter the pixel depth of a grayscale image

COMP6021 Class 07

We looked at how audio might be coded.

The main points were

• analog audio technology - electrical analog for compressed air
• sub-sampling
• quantization level reduction
• relative encoding

Modern audio coding techniques are much more complex in reality

CMOD6001 Assessment 1 Due

All students should submit Assessment 1 using turnitin.com

The course code and password will be set to you by e-mail.

Students will also be expected to discuss their submission in class next week. Failure to turn up to class may result in a student getting zero for this assessment. If you are sick you should get a sick cert from your doctor.

CMOD6001 Class 08

We continued working through the process of writing a paper. Having brainstormed yesterday, today we looked at how to structure all the ideas along various themes. I gave out copies of the white boards from yesterday, and students worked in groups at putting a structure on everything.

We devised a possible outline for a paper.
