Currently most technologies used by virtual studio systems are extended applications of Virtual Reality (VR) technologies. But for small TV stations and web stations, virtual studio based on traditional VR is so expensive while the FLARToolKit technology used by Augmented Reality (AR) technologies is their top option. However, the calculation speed of FLARToolKit is a little slow and the frame rate is very difficult to reach the live broadcasting video level. My improvements are to apply adaptive thresholds, use sample blurring and change identification frequency, which solves the shortcomings and makes the Virtual Studio faster and better.
