Picture this
Scientists at the University of Oxford are developing and improving computer programs that can learn. Often it is useful to feed computer programs a series of images and to get the computer to identify or sort them in some way, but how do computers create or store images?
In this lesson students will explore how bitmap images can be stored or displayed using binary notation, how the image can be compressed using RLE and information about meta-data that is stored with the image.
