Regularized quadratic cost function for oriented fringe-pattern filtering.

We use the regularization theory in a Bayesian framework to derive a quadratic cost function for denoising fringe patterns. As prior constraints for the regularization problem, we propose a Markov random field model that includes information about the fringe orientation. In our cost function the regularization term imposes constraints to the solution (i.e., the filtered image) to be smooth only...

Fast half-quadratic regularized phase tracking for nonnormalized fringe patterns.

Although one of the simplest and powerful approaches for the demodulation of a single fringe pattern with closed fringes is the regularized phase-tracking (RPT) technique, this technique has two important drawbacks: its sensibility at the fringe-pattern modulation and the time employed in the estimation. We present modifications to the RPT technique that consist of the inclusion of a rough esti...

A generalized regularized phase tracker for demodulation of a single fringe pattern.

The regularized phase tracker (RPT) is one of the most powerful approaches for demodulation of a single fringe pattern. However, two disadvantages limit the applications of the RPT in practice. One is the necessity of a normalized fringe pattern as input and the other is the sensitivity to critical points. To overcome these two disadvantages, a generalized regularized phase tracker (GRPT) is pr...

Recursive Least Squares for an Entropy Regularized MSE Cost Function

Minimum MSE plays an indispensable role in learning and adaptation of neural systems. Nevertheless, the instantaneous value of the modeling error alone does not convey sufficient information about the accuracy of the estimated model in representing the underlying structure of the data. In this paper, we propose an extension to the traditional MSE cost function, a regularization term based on th...

N-dimensional regularized fringe direction-estimator.

It has been demonstrated that the vectorial fringe-direction field is very important to demodulate fringe patterns without a dominant (or carrier) frequency. Unfortunately, the computation of this direction-filed is by far the most difficult task in the full interferogram phase-demodulation process. In this paper we present an algorithm to estimate this fringe-direction vector-field of a single...
