Vector vs Raster

Its already in the week 2 for Computer Graphics class . For this week , Madam Ling taught us about vector graphics. She showing us the difference in quality for the vector images and raster images. This is the example that shows the difference.

This picure I took from the goole to show the difference . We been introduced to the analog image and digital image. For the analog image picture is from regular camera . The picture size is infinitesmally and also produce maximum resolution & bandwith while for the digital image is scanned image , CCD or digital camera and its pixel size is finite . Its quality of representation related. Here I give the example of Digital Data .                                                                   

For tutor class Madam Ling taugh us how to change from raster images to vector images by using our pciture in the Facebook .
