22. Distinguishing Traits

Reflect

QUESTION:

After visualizing the day and night images, what traits do you think distinguish the two classes?

ANSWER:

There are many traits that distinguish a night from a day image. You may have thought about the sky: a day image has a bright and sometimes blue sky, and is generally brighter. Night images also often contain artificial lights, and so they have some small, very bright areas and a mostly dark background.All of these traits and more can help you classify these images!

Acc
