A cascade least-squares scheme for wrapped phase extraction using two or more phase-shifted fringe-patterns with unknown and inhomogeneous surface phase shift is proposed. This algorithm is based on the parameter estimation approach to process fringe-patterns where, except for the interest phase distribution that is a function of the space only, all other(More)
We present some results about the parametric complexity for counting the number of truth assignments for two Conjunctive Forms (2CF’s), such problem is denoted as #2SAT. It is common to analyze the computational complexity for #2SAT regarding the number of variables or the number of clauses on the input formula F We consider here, the time complexity(More)
