Summary

The meaning of the name should be clear, but for those who do not know that there was someone on the moon (you know, that giant light-emitting ball in the sky at night) once, they should consider leaving their basement once in fifty years.

Project progress

Initial algo

The initial algo sucked, because it counted the amount of changed pixels in the pictures. A reasonable idea if you got a stable source of image data, but a camera combined with JPEG compression results in epic fail.

Second algo

The second incarnation of the algo checks if an image is between certain boundaries. Those boundaries are generated from statitic calculations on the previous image data captured with the first algo.

The following sets of boundaries are generated:

• dark
  • average
  • minimum
  • maximum
• light
  • average
  • minimum
  • maximum

Here's a test run with a small amount of input data (100 frames containing dark data, 100 frames containing light) download zipped BMP files.

Currently I'm implementing the algo in the Web App, and it will be deployed soon to the server.
