whatever "Z" means. it definitely knows nothing about the z-axis in a 3dimensional space.
The variable is labeled m_zOut throughout the source code. It sure looks like an attempt to map magnitude of the image brightness to the Z axis to me, but then again I didn't write the thing.
but i did ;-) don't know why i named it m_zOut though (i guess, because there was m_x and m_z and "z" seemed to be the natural 3rd variable)

object came up with that value. It's sometimes helpful to know that sort of thing.
right and i am very thankful for the explanation. i just thought that i should give my 2% too.
if you are not sure, experiment with both and see what gives better results
pix_background would come before pix_movement and strip away data which could potentially cause false triggers.
which sounds totally reasonable to me.
well, if he does "NOT want to TRACK anything" but just detect if there is any movement in the image, your suggestion seems to be a bit overpowered (nonetheless it should work fine)
pix_movement + pix_blob give me enough false values that I recommend using additional analysis to give more consistent results. That's all.
right. now it's me who didn't want to contradict anything.
