基于金字塔技术的STL模型数字水印算法
STL Model Watermarking Algorithm Based on Pyramid Technique
摘要
Abstract
To ensure the security and integrity of stereo lithography (STL) model during transmission on the network,according to its own characteristics,the topological reconstruction of the STL model was achieved.After the pretreatment of primary component analysis (PCA),the multidimensional index algorithm for STL model based on pyramid technique was proposed,and the data space that contains the STL model was subdivided and indexed.According to the singular value decomposition principle,an STL model watermarking embedding and extraction algorithm based on B+ tree K nearest-neighbor query was proposed.Experimental results showed that the presented algorithm is efficient and robust to many attacks such as rotation,translation,uniform scaling,vertices reordering,simplifying,noise and cropping under blind detection.关键词
