 Using a green or a blue [http://www.amazon.com/s/ref=nb_sb_ss_i_0_21?url=search-alias%3Daps&field-keywords=photography+backdrops&sprefix=photography+backdrops backdrop] may improve results, but you are not required to use a backdrop if you have reasonable office or home environment with light-color walls and bright lighting.
-== Lighting ==
+==== Lighting ====
 For best results, your environment should have multiple light sources for uniform, ambient lighting. Typical office lighting with multiple light sources located on ceiling should be quite suitable for markeless motion capture. In a home environment, you may need to use additional light sources to achieve more uniform lighting.

 Please note that the system cannot work in direct sunlight. If you plan a motion capture session outdoors you should choose a cloudy, overcast day.
-== Actor Clothing ==
+=== Actor Clothing ===
 Actor should be dressed in solid-color long-sleeve shirt, solid-color trousers (or jeans) and solid-color shoes. Deep, saturated colors are preferable. Casual clothes like jeans should be OK for use with markerless mocap system. iPi Desktop Motion Capture uses clothing color for separating actor from background and therefore cannot work with totally arbitrary clothing.

 iPi Desktop Motion Capture has an option of using T-shirt over long-sleeve shirt for actor clothing. However, simple long-sleeve shirt may result in more accurate motion capture.

 Don’t stand too close to a wall. Shadows on the wall may confuse the system. If standing close to a wall is unavoidable you should use additional light sources to light the wall behind actor to minimize shadows.
 System can have problems tracking push-ups and similar motions because of shadows on the floor. You can improve tracking of such motions by using additional light sources to light the floor.

 Light-color background (light walls and light floor) is recommended for markerless motion capture.
 iPi Desktop Motion Capture is designed to work with real-life backgrounds. A multi-camera configuration (3 cameras and up) can handle certain amount of background clutter. Please keep in mind that the system can be confused if your background has large objects of the same color as actor clothes.
