A CAD Approach for Designing Customized Shoe Last

Accurate reduction of two-dimensional curve noises is crucial to metrology and reverse engineering.In this paper we propose a set of schemes for two-dimensional curve denoising.Our approach consists of three main steps: 1) feature-based pre-smoothing of noised polylines; 2) curve partitioning of polylines into different regions; 3) two hybrid denoising schemes of arbitrary polylines with noises.Numerical experiments indicate the effectiveness of our approach against existing methods.
