An Improvement to Unscented Transformation

This paper proposes a new sigma point selection strategy to better capture the information of a probability distribution By doing so, the non-local sampling problem inherent in the original unscented transformation (UT) is fundamentally eliminated It is argued that the improved UT (IUT) outperforms the original UT at the cost of increased but comparable computation burden and will be useful in constructing a nonlinear filter.
