Found this nice tool

Can be used on- and offline.
Its not realtime and only on stills but still helps to check positions and changes

Hi Joan


The "paint" version would be nice indeed but has the downside of being labour intensive if you want to compare multiple positions.

The green screen solution has a margin or error, this mainly depends om the lighting of the subject (and clothing choise) and the background, but in general I this this margin will be small enough. Green or blue screen is higly tested in film and profided you set it up correctly works very well

is a software tool that uses a webcam (and is way to expensive for me ;-)  )

There where some apps for Apple as far as I know but couldn't find a working app for  Android.

And in PS one could use the histogram to count the pixels or percentage of a color(range)

Hi there,

I've been trying out Kinovea for a while now and like it a lot!! Thanks.

My use is mostly with bike fitting, getting my self aero. So my feature request is... would it be possible to build a tool (or is there a tool) which would measure/count the area of a certain color (green screen) so one can determine if the frontal area is getting bigger or smaller with a change of postion on the bike?

Would be great is this was a "live" tool so one could see on the spot if a postion change is positive or negative in regards to the frontal area.

I hope this makes sense.

Can imagine this would be a usefull tool in others sports as well
