6. One franchise built around pixel art...
Pokémon Red (released 1998)

7. Using Pokémon as a training set
● 64 x 64 x 3 pixels = 12,228 features per image
● 700+ Unique Pokémon
● 76,000+ animation frames

8. Feature engineering with images
● database used for eliminating shape outliers
● 231 Pokémon selected (19,231 frames)
● Expansion of training set size:
○ Brightness
○ Hue
○ Contrast
○ Left-right transformations.
