Create a new Processing file and save it as

Lab$03$bChromaKey$\_$yourLastNameFirstnameInitial.pde.

$2)$ Find minimum two images:

a$)$ One image with either blue or green background filmed.

You might even consider to photograph$/$film yourself. Could

use Google to find these images, or just create it using any

imaging tool $($e$.$g$.,$ Photoshop$)$ by adding one object against

blue $($or green$)$ filled color as background.

b$)$ The other image contains a unique visual appealing $($visual

effects$)$ used as background plate. If you are familiar with

Photoshop, feel free to use any Photoshop filter effects. Or

use your custom filter from Lab$01($to save your work as an

image file, use save$()$ in Processing.

$3)$ Design an algorithm $($e$.$g$.,$ if$-$else conditional statements or loops

to segment certain regions$)$ to extract$/$modify blue $($or green

depending on your background plate. Then, composite$/$combine

with the other image as a foreground object. Review some

example from Pixel operation in Processing.

$4)$ Add a key $($or mouse$)$ interaction for more visual effects $($e$.$g$.,$

change foreground$/$background plate, applying filter etc.$)$
