The Image Quality and Computer Vision Topics

The Single Pixel Attack contextualizes why Image Quality matters

Have you have heard of the single pixel attack? This is where researchers fooled a simple classification network by changing a pixel.

 This adversarial research turned a ship into a car, a horse into a frog, a deer into an airplane!!

While this research is independent from embedded vision systems, it's not a far reach to imagine something similar in the real world.​ Other researcher have extended this effort to the field and we quote:

“Nonetheless, we show some examples of situations where nearly imperceptible image modifications can result in dramatic perception changes. ​ ​ Even in applications without malicious people trying to trick your system, the natural world, [your camera hardware, and image processing pipeline] may be adversarial enough.”
