Resumen
Abstract. An important step in fringe pattern analysis is the
so called phase unwrapping. Although this task can be
performed easily using path dependent algorithms, most
times, however, these algorithms are not robust enough
specially in the presence of noise. On the other hand, path
independent methods such as least-squares based or
regularization based may be little convenient due to
programming complexity or time consuming. In this paper
we describe an alternative algorithm for phase
unwrapping based in the determination of weights to
linearly combine a set of radial basis functions (RBFs). As
described, our algorithm is fast and can be easily
implemented following a simple matrix formulation.
Numerical and real experiments with good results show
that our method can be applied in many kinds of optical
tests.
