+====== Marker-Based Motion Capture Overview ======
 Marker-based motion capture systems can be split into passive and active systems.
-**Passive marker-based systems** generally use retroreflective markers placed on the body in accordance with a particular marker set. Cameras are set up to record the near infrared light reflected by these markers and estimate the 3-dimensional position of these markers throughout the movement. A model, essentially a mapping from markers to the skeleton, providing these marker positions with biomechanical meaning is defined by the user and this model is applied to the recorded 3D marker positions during dynamic movements of interest to produce pose estimates.

 **Active marker-based systems** generally use markers that emit light, which are placed on the body. Cameras record the light emitted by these markers and estimate their 3-dimensional position throughout the movement.
