DEVELOPMENT
WEEK 1
Early on ln the project we picked the subject of compression to work around.
We looked into a few different kinds of compression, the history of compression and the relationship between compression and our project.
When computers, personal computers in particular, were upcoming compression was very needed. Data wasn’t usable because files were to big and computers to “slow”. Files needed to be smaller for the computer, but had to remain the same quality for humans. For example audio files had to be smaller, but still had to sound good. Images had to exist of less data, but still had to look good. Algorithms were created to do exactly this.
QUADTREE ENCODING
Quadtree encoding is a compression method which is used in JPEG compression and is based around a fairly simple concept in which the computer doesn't need to save the information for all the pixels in a image. It keeps dividing the picture into sections which have more or less the same color. The computer just has to remember how many times and where he split up the picture.
Above you can see two images which have been compressed with a quadtree system. The one on the left has been to told to split up fewer times than the one on the right so you can see the different sections in which the computer divides the image.
