Estimation Track–Before–Detect Motion Capture Systems State Space Spatial Component

Part of the Lecture Notes in Computer Science book series (LNCS, volume 4673)


In the paper spatial component estimation for Track–Before–Detect (TBD) based motion capture systems is presented. Using Likelihood Ratio TBD algorithm it is possible to track markers at low Signal–to-Noise Ratio level that is a typical case in motion capture system. Three kinds of TBD systems are analyzed and compared: full frame processing, single camera optimized and multiple cameras optimized. In the article separate TBD processing for every camera is assumed.
