decided to change frame comparison functions again from optical flow to
a home brewed function that compares gray levels in the pixels of each
frame. significant differences in gray levels between the frames can
potentially trigger a motion event.
also moved away command line arguments to an external config file to set
app parameters.
created a README file to get this project ready for general open source
release.
all current experimentation with the code leads up to this point
for optical flow motion detection. the code as it stands will
input frames in pairs and then compare each pair of frames for
any significant changes in the optical flow distance between
points.
experiments have shown that this actual does work fairly well;
however there is significant amounts of CPU usage and video
encoding options are not flexible at all. the code still picks
up false positives but I have high confidence something that
can be adjusted through external parameters which I will
impliment in the future.
