这个周开始要着手实现网格水印的代码了,虽然还什么都不会,但也只能一步步摸索着往前走了. 我要实现的论文题目是<<Watermarking 3D Polygonal Meshes in the Mesh Spectral Domain>>,之前的博客中有过这篇论文的理论分析,看起来貌似不难,但动手实现起来的时候还是挺困难的.首先要解决的问题就是配置实验环境. 一开始我打算用Eigen对拉普拉斯矩阵进行特征值分解,因此就涉及到Eigen的配置.Eigen是一个开源的矩阵运算库,里面封装
Problem Description A single playing card can be placed on a table, carefully, so that the short edges of the card are parallel to the table's edge, and half the length of the card hangs over the edge of the table. If the card hung any further out, w
