CMOD6001 Class 15

This was an optional class. 3 students came along to discuss the project.

Some things that came up

Need to pick group fairly soon
any song
doesn't need to be one take

CMOD6001 Class un-cancelled

The thing that would have cause me to miss today's class did not come to pass. However, having cancelled the class I am not now going to un-cancel it.

I will be in the room though ans any students or groups that want to meet with me to discuss the assessments and projects can do so.

COMP6021 Class 14

I showed students what they needed to do in Photoshop to complete the assignment. I gave out images, but students are also free to choose their own.

CMOD6001 Class cancelled 20 Oct 2010

This Wednesday's class is cancelled. Apologies for the short notice.

COMP6021 Class 13

We fixed the in-class assessment date for next week. 1200 26 Oct 2010. B229.

We looked at color lookup tables (CLUTs) and dithering. We put some numbers on dithering and saw two examples. Check the podcast feed for more examples.

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

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 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.
