I am not going to watch 8 hours of someone sleeping, I'll just get a computer to do that, so I learned some basics for "computer vision" in R.
Here I am using frame subtracting by importing each greyscale frame from the depth camera and subtracting it to the next frame. This way I can identify changes and how small/large are these changes between each frame.
Here is a sample,

Please check out the first part of my sleep monitors series first.
Back in May 2011, unsatisfied with the "software" solution I developed with the first prototype, I started developing a "hardware" based solution to develop a contactless sleep actigraph monitor.
And that's what I came up with:

A few years ago, I was looking to improve my sleep. Measuring it would be a start. However I was not satisfied with any sleep monitors on the market.
