Image compression

A big thanks to Colin for putting me on to this YouTube channel. As we saw in today’s lesson computer images (digital) can be very large. In order to save space when we save them we must compress them. We can either do this in a lossless fashion or in a lossy fashion. With lossless you can always get back to the original without any corruption this is not possible in lossy compression.
