基于曲面特征的三维半色调处理算法
Three dimensional halftoning algorithm based on surface features
摘要
Abstract
The mechanism of three-dimensional printing is discussed and the concept of Three Dimensional Halftoning Algorithm is proposed. The algorithm is based on three-dimensional surface features. First, by investigating the reason for color distortions during 3D printing, the impact of the Gauss curvature is obtained in three-dimensional surface; Second,the Gauss curvature is introduced into the Three Dimensional Halftoning algorithm, and the threshold quantizer is improved; Finally, the path of the halftone processing can be optimized, and the three dimensional halftoning algorithm based on surface characteristics can be proposed. The experiments prove that the algorithm is effective in halftone processing operations of three-dimensional printing.关键词
