Abstract : The primary goal of this study is to develop an improved algorithm for space-time interpolation of gappy frontal data sets. The major improvements are the inclusions of (1) two-dimensional phase speed, (2) a more autonomous algorithm, (3) a better feature matching algorithm, and (4) the inclusion of a temporal smoothness constraint. The space-time interpolator is formulated in framework of probabilities (Bayesian) estimation. This report first reviews such an estimation theoretic framework and, in particular, a Kalman filter-based interpolation algorithm. Then, feature detection and matching algorithms are discussed, followed by presentation and discussion of some preliminary results
