1. A method for updating a predicted location of an object in a multi-dimensional space having a plurality of (n+1) dimensions, the method comprising: reading, by a computer system, a first probability density function representing a first location of the object on a cylindrical multi-dimensional space ( n × ) of the multi-dimensional space; receiving, by the computer system, a second probability density function representing a second location of the object on the cylindrical multi-dimensional space of the multi-dimensional space; fusing, by the computer system, the first probability density function with the second probability density function to form a third probability density function representing a third location of the object on the cylindrical multi-dimensional space of the multi-dimensional space; and providing, by the computer system, the third probability density function as an indication of the updated predicted location of the object in the multi-dimensional space.
