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.”

Surveillance?

Our low F#, high resolution lenses are suitable for 180° dome cameras, low light, and active IR illuminated scenes.

Aerial Robotics?

Our light-weight, miniature lenses are ideal for collision avoidance, long-distance viewing, and end-customer viewing.

Does it Require an IP65+ Lens?

We offer IP65+ variants of many lenses. These are suitable for applications  exposed to the environment, without a window.

Surveillance?

Our low F#, high resolution lenses are suitable for 180° dome cameras, low light, and active IR illuminated scenes.

Consumer / AR+VR?

Our high resolution fisheye lenses will let you design 360° cameras and and stereographic lenses are equivalent to "GoPro" lenses.

Video Conferencing?

Our wide-angle, low distortion, high resolution M12 lenses result in optimal object deformation without post-processing.
