Webirls circle or cylinder estimation methods perform automatic outlier assigning through iterative reweighting with M-estimators, followed by a Nelder-Mead optimization of squared distance sums to determine the best circle/cylinder parameters for a given point cloud. The reweighting strategy used in TreeLS is based on Liang et al. (2012). WebThis research is developing a new and significantly better method for the design of a wide variety of digital filters. The new method is based on a successive approximation algorithm called Iteratively Reweighted Least Squares (IRLS). One form of IRLS, Lawson's algorithm, has been used before but not extensively because of slow and inconsistent ...

WebAug 16, 2024 · Theoretical basis of the IRLS‑FT method The developed algorithm uses series expansion based discretization of the Fourier spectrum with Legendre polynomials as basis functions of discretization, and the solution of an inverse problem provides the estimated values of expansion coefficients.
WebThe entire process is robustified using the IRLS method by the application of Steiner weight instead of Cauchy, thereby enabling an internal itera-tive recalculation of the weights.
