What's Up p
In two afternoons:
Learn how to write programs in Python Learn how digital images are stored in the computer Use Python programs to change images and create new ones!
Of course we won't learn everything there is to know in two days, but we'll make quite a start!! we ll
Credits and Links
These slides and ideas are largely taken from the media computation project at Georgia Tech
For software, links, etc. (for home – we already have what we need on the lab computers for today)
JES software: http://coweb.cc.gatech.edu/mediaCompteach/26 More sample media, etc. http://coweb.cc.gatech.edu/cs1315/814
Thanks to Mark Guzdial and to Barbara Ericson for suggestions and advice

Get the book!
More Python More about images Movies, sound More CSE!
Workshop Plan p
Today
Python basics
Python as a calculator; variables, expressions and assignment Defining simple functions
Digital images
Representing pictures: pixels, rgb values Simple image transformations: loops Conditional statements (if time, otherwise tomorrow) ( )
Tomorrow
More complex image manipulation; image coordinates, nested loops p
Both days: Some talking, plenty of hands-on tinkering
Introductions
Who are you Where are you from What's your plan at UW y What do you want to get out of this workshop
Python y
The programming language we will be using is called Python
We didn't invent Python—it was invented (and named) by researchers across the Internet http://www.python.org It s It's used by companies like Google Industrial Light & Magic Nextel Google, Magic, Nextel, and others Named after Monty Python – not after some sort of snake
