SSIM Code

Image comparison using SSIM. It can be used to detect image
differences... but, the algorithm was designed to compare image quality
and look at compression artifacts. Anyway, it works kinda okay for
detecting frame differences.

Add linear regression
...
For easy line following mainly. In non-robust mode the line is computed
using least squares. In robust mode the line is computed using the
Theil-Sen median of slopes method. We do not use the Siegel Median of
Medians operation because it costs more CPU time... but, more
importantly there's no way to improve the centroid estimate so even if
the slope is more robust the line will be drawn in the wrong place.

Add Image Writer/Reader
...
These two new classes allow you to record image data for later viewing
at the same speed the image data was recorded. Unlike GIF/MJPEG the
image data is stored on the file system completely uncompressed in
native frame buffer format making super fast reading and writing
possible. Recording VGA Grayscale at ~13 FPS is possible along with
playing it back. (That's about 30 Mb/s folks).
...
The motivation for writing these scripts is so that you can record video
of something like a line following track, take that video home, and work
on computer vision algorithms for that data.
These classes should make it a lot easier to use the camera at home now.
