Mask-Atari

Learned Examples

(Left: only masked area is observable Right: area without mask is transparent for easier understanding)

Breakout

Asterix

Mask Parameters Setting Examples

Scale

(Left: Scale 70 pixels Right: Scale 130 pixels)

Speed

(Left: Speed 10 pixels/frame Right: Speed 50 pixels/frame)

Number

(Mask number = 2)

Boundary slipping through (when set to True)

Resolution Decay

--resolution is decayed with 3 layers by taking the smallest mask as the centric area with 1.0x resolution.
