Halovision 1.0.5

Added facial detection so that it only looks for movements within a region where a face was detected.

The file haarcascade.xml can be replaced with one of these or a custom cascade classifier for better performance.

The latest version of the Halovision device; code-named INSPEC. A standalone infrared camera with a processor powerful enough to run the latest machine vision algorithms that flash LEDs when eye-movement patterns are detected after a long enough still phase. The camera case is 3D printed and installed on a flexible tripod to get a good angle. It records GIFs along with BMP stills that can be viewed the next morning via micro-USB cable.

Halovision 1.0.2

Improved the algorithm… it was missing REM episodes where the eye movements stopped for more than 5 seconds before the stairway to heaven was reached.
Episodes like in the following minute, where there is a 10 second break in eye movements around the 30 second mark, will now keep counting and trigger the audio tracks:
