Week 6- Muddy

If I were to go back in time, I would be excited to tell people all about the innovations and technology that we have in today's time. But take image technology for example. As I think about it, they would ask me "Well, how does that work? How did they do that?" and quite frankly, I wouldn't know. I see pictures and use cameras, but I didn't know any of the concepts behind what makes these things display images. After some research and gaining knowledge of the subject, I found it interesting how images appear in our everyday lives.

Images are made up of many little dots of color, or pixels. These pixels arrange in a way that come together as a picture. A common type of graphic is called Raster. It uses the groups of pixels to create a "bitmap" which we perceive as a picture. Using Raster graphics, problems occur when you try to expand, zoom, and scale pictures. If you zoom in far enough, the picture gets distorted because you start to see the groups of pixels instead of one clear picture. This is when you get blocky or jagged pictures. Vector graphics gets rid of that problem. It arranges the picture using "primitives" or by geometric shapes that can be created mathematically. This way if you want to zoom in, math can be using to scale the picture down while keeping the quality of the image.Video: Raster vs. Vector Images

Images can also be compressed to save filing space. Technology has found different ways to make image files simpler. One way is called lossless compression. This method eliminates redundancy in the pixels. Lossy compression, which is another compression technique, discards some unneeded things in the image. Like images, audio and video files can also be compressed. This is an important fact to know in the business environment. Because a business has to keep record of many things, it is always key to know how to save space, which can help you save money.
