ICP Algorithm (Classic Implementation) with Moving Least-Squares Enhancement for Curve and Surface Fitting

Development of a curve and surface fitting method based on the Moving Least-Squares (MLS) approach, which significantly improves upon traditional Least-Squares (LS) methods. This implementation yields fitted curves and surfaces with higher accuracy and superior smoothness characteristics. Detailed explanation of MLS algorithm principles, including weight function implementation and neighborhood point selection strategies for optimal surface reconstruction.
