Social Light Flex Module

We will be using OpenCV to help process and recognize flashing LEDs.

We have read papers that stat it is around 15bps maximum when transfered phone flash to camera. We figure if we can recognize specific spectrum components that we can increase this significantly.

So far we have had trouble finding near IR LEDs that don't also emit a red as well.

We have been testing more frequencies of LEDs. We have had some success around 770nm on the near IR side. However, it is clear that humans see UV much better than cameras. So that will require additional work to find camera distinguishable frequencies that are near IR.
