Testing Color Analytics Performance

Author: Ethan Ace, Published on Dec 16, 2013

In an industry known for overhyping its own value, color analytics have been considered pure science fiction, with few, if any, stories from the field to back up manufacturer claims.

In this report, we test Bosch's IVA color analytics to see which practical applications they performed in, and where they failed.

First, in an interior conference room with a human subject:

And an outdoor parking lot/driveway with different colored vehicles:

We varied the precision of the analytics to understand how performance varied, from least to most sensitive using their built-in scale:

We then tested a variety of colors from red, green, blue, orange, neons, etc.
