Hello,how can i build a simple motion indicator?For example; i want it to show a single value between let's say 1-100 where 1 would be no motion at all and 100 would be huge amounts of movement like the shaking of a handycam.

One of the biggest background subtraction libraries out there, bgslibrary, has tons of algorithms doing exactly what you need (https://github.com/andrewssobral/bgsl...), the more front movement, the heavier your indicator!

Try looking at different image stabilization algorithms. They have to determine the motion to compensate for it, so you can use that as your metric. Determining what the 100 end of the scale is would be a situation dependent thing, where you analyze a bunch of videos and rate them yourself then pick the best fit.
