Least Square Approximation and Analysis for Scattered Data Based on Orthogonal GF System
摘要
Abstract
Base on GF system,an orthogonal representation algorithm for scattered data is proposed. When k=0 and k=1 ,GF system are Haar functions and Franklin functions respectively.A new energy model is proposed to solve this problem based on GF system.According to GF spectrum,different hierar-chical surfaces could be reconstructed for scattered data.The experiments show that the method proposed is efficient and can produce pleasing results.关键词
