COMP6023 DCOM1 Class 30 Transparency & PNG

We looked at transparency and the PNG format.

We discussed the merits of GIF, JPEG, and PNG, and in which circumstances which might be the best choice.

COMP6021 Class 32 Tutorial

Today's class was a tutorial. We looked at dithering questions from the set of sample questions.

Working out the weighted average of the RGB values is easy enough. But generating a dithering pattern from a patent and a target simulated colour, is a bit trickier.

Students should expect a dithering question on the summer exam.

COMP6021 Class 30 Block Matching Algorithms



We looked at sub-optimal block matching algorithms (BMAs) for motion compensated video compression. I got the feeling that students weren't especially interested in this.
