Color and colorspaces

 Numbers and Java

 Feature detection

Globally define thresholds

 Self-calibrate for different lights

 Use the gimp/bot client on real images Getting an image performs a copy



 Int[] = bufferedImage.getRGB(…)



 Getting a pixel performs a multiplication

 int v = bufferedImage.RGB(x,y)

 offset = y*width + x

 Memory in rows, not columns…so go
