We use techniques from … WebMar 5, 2024 · The moving least squares (MLS) and moving total least squares (MTLS) are two of the most popular methods used for reconstructing measurement data, on account of their good local approximation accuracy. However, their reconstruction accuracy and robustness will be greatly reduced when there are outliers in measurement data.
WebThe paper introduces a robust moving least-squares technique for reconstructing a piecewise smooth surface from a noisy point cloud. The method introduces the use of a new robust statistics method for outlier detection: the forward-search paradigm. The algorithm classifies regions of a point-set into outlier-free smooth regions, which WebIn cases where they differ substantially, the procedure can be iterated until estimated coefficients stabilize (often in no more than one or two iterations); this is called iteratively reweighted least squares. In some cases, the values of the weights may be based on theory or prior research.
