Facial Motion Capture:
Facial Motion Capture is the process of electronically converting the movements of a person's face into a digital database using cameras or laser scanners.

Shoot a nice footage with a dialog and some facial gestures .
Variety of techniques are used to do motion capture
Motion capture

Production Technique
it depends on how high or low quality Footage u have shoot.

2D and 3D are other two types of tracking by which motion capture.
3D:
To capture 3D motion, we need more then 2 cameras to tracks 3D co-ordinates of one tracking point.
eg: avatar motion capture which tracks human character movement.
specific trackers/ sensors are used to track the actual co-ordinate of the sensor.
Advantage/Disadvantage:
That 3D position of the tracker is perfectly captured captured and it can be played in real time
but can be very expensive and can also need special software to Capture
2D:
Only one camera used in this tracking data,which is Rigged to face with a setup to track head movement
Data can only be captured in X and y,coordinates, no depth is involved .more important to have a stabilized camera
Advantage/Disadvantages:
It is cheaper to do but tracking will have to be done manually with tracking software eg,Nuke,PF Track etc.
disadvantage is that you wont get this in real time .This technique is also used in avatar for facial capture
This setup requires a light weight camera which is mounted on a helmet or a cap attached to head.
If wired then will have to connect that camera to the system.
Camera should have sustainable frame rate- 30FPS- 640*480
Characters head should be very much stable and aligned to camera.
if moved than the animation will give unnecessary movement to the character
Markers:
2D markers should be easy and removable eg, eyeliner.
Light should be proper, not to bright not to dark .avoid highlights and grains on the tracking markers
decide the amount of markers which need to be placed for the character movement
more the markers more the quality of the animation we get from the tracking data
Fewer markers are good for games kind of animation .
The placement of the markers should be according to the bone setup of the character .
meaning they should be in the same general area of the face .
