Multi model tracking for localization in wireless capsule endoscopes

In this work, the tracking of a Wireless Capsule Endoscope (WCE) is considered. The special shape of the movement track in the small intestine has been taken advantage of to model it as a multi mode random process. Then two Multi-Model (MM) target tracking methods have been adapted to follow a source which is moving based on the proposed random process. Thus the goal is to study the adjustability of the MM methods to the intestinal track. Through simulation it is shown that such methods are able to reach far better accuracy than a simple triangulation which is currently used in the prevalent WCEs.
