Image manipulation and computer science

Lee Willis, North East Futures UTC

Description

Ever since the first photo was developed people have been manipulating images. Originally, this was the preserve of the photographer in their dark room. With digital photography, it is now as simple as applying filters to photos using tools such as Photoshop or Instagram - bringing magical results to the masses. But it is not magic! It is just the transformation of data representations. In this session we will use both unplugged and computer-based activities to explore computer science through image manipulation. Tools such as Pixel Spreadsheet (http://coweb.cc.gatech.edu/mediaComp-teach/54) and the JES environment for media computation (https://code.google.com/p/mediacomp-jes/) provide engaging and accessible ways to get behind the magic! This session is based on the presentation by Roger Davies at the 2014 CAS National Conference and the work of Mark Guzdial and Barbara Ericson on a multimedia approach to teaching CS.
